New insight into dogs' fear responses to noise

Feb. 18, 2013 ? A study has gained new insight into domestic dogs' fear responses to noises. The behavioural response by dogs to noises can be extreme in nature, distressing for owners and a welfare issue for dogs.

The research by academics from the School of Veterinary Sciences at the University of Bristol, and funded by the RSPCA, is published in Applied Animal Behaviour Science. The study provides an important insight into dogs' fear of noises, and could improve our understanding of behavioural signs of fear or anxiety.

In the study two approaches were taken to investigate the occurrence of, and risk factors for, these behaviours: a postal survey of dog owners to investigate general demographic factors and a structured interview of a sub-set of owners to gather more detailed information.

Almost half of the owners who were interviewed reported that their dog showed at least one behavioural sign typical of fear when exposed to noises such as fireworks, thunder and gunshots, even though only a quarter had reported their dog as 'fearful' of noises.

This suggests that whilst they are aware of their pet's behavioural response when exposed to a loud noise, owners do not necessarily recognise this as being indicative of fear or anxiety. This has relevance both for awareness of compromised welfare, and the methodology for surveying such behaviour.

The most commonly reported behavioural signs were vocalising, trembling/shaking, hiding, vocalising and seeking people. It is thought trembling and shaking are more often reported by owners than other behaviours because they are similar to fearful behaviours in humans.

Other behavioural signs, such as decreased activity or salivation, may not be as easily recognised by owners as signs of fear, and may be under-reported. Also, signs of urination, salivation and destruction may make owners disappointed or angry, and this may influence their interpretation that such behaviours are associated with fearfulness.

Responses to fireworks were the most common, but fear responses to loud noises such as fireworks, gunshots and thunder appear to commonly co-occur, suggesting generalisation between salient stimuli.

The risk factors for owner-reported fear of noises included breed, although 12 breeds or breed types were less likely to show fear responses to noises than cross-breeds, including popular gundog breeds such as the Labrador, Cocker Spaniel and Springer Spaniel; age, where risk increased with age; and origin, where dogs living with the owner who bred them had a reduced risk compared to dogs purchased from the breeder by a second owner, supporting the view that an early environment that is very similar to the environment experienced in adulthood is advantageous.

The researchers suggest a dog's early life experience is an important factor in the development of fear responses to specific loud noises.

Dr Rachel Casey, European Specialist in Veterinary Behavioural Medicine and Senior Lecturer in Companion Animal Behaviour and Welfare at Bristol University, said: "Our results suggest that the characteristics of dogs, their early environment, and exposure to specific loud noises are involved in the development of fear responses to noises. Interestingly, less than a third of owners sought professional advice about treatment for their pet's response to noises."

Disappointingly, less than a third of owners currently seek professional advice about treatment for their pet's fear. The researchers recommend there is a need for veterinary surgeons to increase awareness among the general dog owning public that treatment is both available and effective in dealing with fears of loud noises, and to direct them towards appropriate sources of help.

Obama to speak at Morehouse College commencement

PORT ST. LUCIE, Fla. (AP) ? A White House official says President Barack Obama will deliver the commencement address at all-male Morehouse College in Atlanta this spring.

The Rev. Martin Luther King Jr. is among the historically black institution's alumni. Commencement is scheduled for May 19.

Obama typically speaks each spring at a handful of college and university commencement ceremonies, including at one of the military service academies.

Last year, he spoke at commencement ceremonies at all-female Barnard College in New York.

The White House official declined to speak for the record because the schedule of Obama's commencement speeches has not been released.

The Atlanta Journal-Constitution first reported on Obama's address at Morehouse.

Ride The Search Engine Optimization Train To The Success Station ...

TIP! Use the longer or plural form of keywords to generate more search engine hits. Keyword stemming is a tool used by some search engines.

An essential part of online success is using search engine optimization to compete effectively with other sites in the search results. Search engines are the online traffic cops that direct people to various sites based on their search queries. Using the helpful tips contained in this article, you can quickly boost the amount of traffic reaching your website.

TIP! For a good affiliate marketing strategy set up pay-per-click advertising. This is a simple system with low pay, but you can make money from it.

Use the ?alt? tag on webpage images to maximize SEO. These tags replace images if the image display is disabled by website visitors. Search engines dig through and read the alt tags so ensure that they contain your vital keywords.

TIP! Spiders sent out by search engines are constantly on the lookout for fresh content. A blog is an excellent way to attract these spiders because you can update it constantly.

Be sure to ask lots of questions before deciding to outsource SEO work. Determine how knowledgeable the company is about your industry, what kind of SEO techniques they employ, when you can expect to see results and how much it will cost. You should also view some of their prior work, and talk to formal customers. A reputable company will have no problem doing this.

TIP! When you make the most of SEO it will boost your business. This is a fact some businesses are not aware of.

Marketing online is all about search engine optimization (SEO). Putting the proper keywords throughout your content will give you a higher ranking on search engines, giving you more traffic. This is the best way to bring people to your site.

Search Engines

TIP! The text on your site should be large enough for most people to read. Adding interactive functions to your website, like allowing users to change the font to their preferred size, can help to build your online reputation.

Make sure you employ SEO tactics in your articles. This means striking a delicate balance between including the keyword enough for the search engines to notice while not making the text sound awkward. Since search engines evaluate the density of keywords, your site?s search engine rankings should improve dramatically.

Think as a consumer when selecting search engine optimization keywords. People will use easy terms when they are looking for something.

TIP! Use descriptive title tags so that the search engines can easily find and read your content. Search engines usually will not show content past 60 characters.

If you don?t know how to optimize your website content, then work with a company who specializes in SEO services. SEO techniques are the most effective way to get your website to rank highly in search engine results. You will find a number of companies offering SEO services on the Internet, and can look for the best deal.

Search Engine

TIP! This will greatly increase search engine ratings for your website. Your meta description should serve as a simple call to action, since it will appear under the site hyperlink in most search engines.

When you create your own search engine, you control how specific or general its results are. Clear commands and search parameters often improve the functionality of any nascent search engine.

TIP! If you publish your web content in another language and not english, be sure to use the ?language? meta tag. You will get a higher rank in the search engine if someone searches using that particular language.

Be certain each single tag is unique for each page when using meta description tags. Using the exact same content in all of your meta description tags is frowned upon by the algorithms that the search engines use to rank you.

Google has the power to penalize your site for creating redundant content. Instead, think of something new to write about to attract a different audience.

TIP! Placing your keywords strategically in the context on your site will help increase the traffic the search engines bring your way. Use keywords at the beginning of your text, but avoid stuffing.

Be sure to position your keywords within your site map. Site maps are excellent navigational tools as well as helpful for search engine optimization. This can affect your search engine rankings, as content that is easy to find is considered more relevant.

TIP! To increase your online presence, utilize the local listings on Google and Yahoo. These listings provide your website with free publicity, and should increase your website?s traffic.

One of your main goals when trying to reach a high search engine ranking should be improving the quality of your content. One way to drive traffic is to offer content and information that is unique and exclusive to your site. High-quality, unique content not only draws more traffic to your website, it is also more likely to turn a first-time visitor into a repeat visitor.

TIP! Before beginning a website, research information about your keywords. The keywords should be referenced throughout your website and in the titles of your articles.

Keep your content fresh by writing and posting new content as quickly and as often as possible. Commit yourself to publishing a certain number of stories each week. Search engines place a higher value on websites that publish new content consistently than on websites that rarely or intermittently produce new content. Sites that always have fresh content rank higher than those with stale content.

TIP! If you sell a product or service, you must keep in mind that offering information which readers find useful will rank you higher than your competition who focuses only on selling. Post relevant articles about the products you sell.

Even if all of your content is about the same topic, keep each title or heading interesting, attention-grabbing and unique. The word count of titles should not be high, because more words means the individual words have less impact, and the ones towards the front are very important. The first few words of your title are the words that a reader is going to catch. Make those words attention grabbing to make the reader want more.

TIP! To make your site more noticeable you should use a lot of keywords; even ones that are misspelled in the meta tag area. The search engine algorithms will pick up on these tags and show your site when people search for these keywords.

Search engines will lower your page rankings if you are found to be manipulating the rating system to artificially achieve top search rankings. Some companies, such as Google and Yahoo, ban companies from appearing in their ratings at all. Be aware of the methods you use to optimize your search engine rankings.

TIP! If you want to maximize the impact of your SEO campaign, don?t overlook your server headers. Poorly set-up server headers can be a big roadblock to success.

Each page on your website should be optimized for one keyword phrase. If you try to include too many keywords on a page, it will get confusing. When you focus your efforts on one topic and one keyword, it makes it easier for readers to understand your content, so they are more likely to enjoy it and return for more. Search engines may help bring visitors to your site, but they will not endear it to readers. Search engine optimization is important, but the experience of your readers is even more crucial.

TIP! The title that you create needs to have your keyword included for search engine optimization purposes. So that everything is linked together, include the title tag on all of your site?s pages.

Getting the owner or CEO of a company to begin blogging can be a valuable tool to increase site traffic. Your customers will want to read something from the head of the business.

Search Engines

TIP! People might come to your website in droves, but if they click away after 5 seconds, it?s not going to help much. There is evidence that the more time a person is on a site the higher ranked that site will be.

Successfully optimizing your site for search engines may seem intimidating, but as this article has shown you, it doesn?t have to be difficult. Knowing the few basic principles that determine how the search engines work, can help you tweak your site to attract more visitors than ever. Before you know it, you?ll have a slew of new customers.

Up to 10 inches of snow forecast in Mass.

Janet S. Carter / The Free Press via AP

Snow flurries shroud Washington Street in Kinston, N.C., on Saturday.

By Gil Aegerter, Staff Writer, NBC News

Whiteout conditions in the Detroit area on Saturday caused pile-ups involving dozens of cars and trucks that closed several highways, including Interstates 75 and 94, all part of a weather system that brought winter storm warnings for parts of Massachusetts.

The largest crash was on Interstate 75, NBC station WDIV reported, citing police in Woodhaven, but I-94 also was closed temporarily. There were reports of injuries but no fatalities in the 44-vehicle crash on I-75, the Detroit Free Press reported.

The National Weather Service issued a winter storm warning for eastern Massachusetts, including the Boston area, and Rhode Island through 7 p.m. ET Sunday. Up to 10 inches of snow accumulation was possible for some areas on Sunday, the weather service said.


The culprit is a large dip in the jet stream that brought colder-than-average temperatures to the eastern U.S., weather.com reported -- resulting in freeze warnings for parts of northern Florida.?That was combined with a low-pressure system heading north that was expected to be off New England Sunday morning.

Snow was falling in the Carolinas, but that was expected to end Saturday night, weather.com said. Maine could get more than 6 inches. Snow also was possible across Connecticut.

Weather.com said there was high degree of uncertainty about the snowfall total: "A slight jog in the track of the low to the east or west could result in less or more snow for the locations in New England highlighted above."

Much of New England just finished digging out after a historic winter storm that dumped 30 inches of snow on parts of Massachusetts and even more in Connecticut.
