Dog walkers, please be watchful the week following Halloween. While dogs are never allowed chocolate, they are mysteriously drawn to it and some doggies can spot and swallow a chocolate bar wrapper, dirt and all, in seconds.

That’s where Paula Szuchman and The Wall Street Journal come in. Szuchman had her pup’s DNA tested with four popular dog DNA services. See her full article on the topic here, as well as her helpful chart on how the tests compare.

Acidophilus is a probiotic often found in yogurt that aids in digestion: it puts the good bacteria in your system! Check with your vet to see if giving your buddy this supplement will help that sensitive stomach.

But our dogs need some bacteria to remain healthy. In order to ensure that the good bacteria is not depleted by a dose of antibiotics, it is a good idea to administer a probiotic to your dog after a round of antibiotics. It won’t do any good to give probiotics at the same time as antibiotics, but once the antibiotics are completed, probiotics should be given for roughly the same length of time that the antibiotics were prescribed. It is possible to purchase dog-specific probiotics, but human quality probiotics will work as well.

Always discuss use of pet medications with your vet before you make any decisions as to treatment.

The significant health threat secondhand smoke poses to pets is through oral cancer and lymphoma in cats, lung and nasal cancer in dogs, as well as lung cancer in birds. There is also a strong correlation between secondhand smoke and certain forms of cancer in cats. There are higher incidents of mouth cancer in cats living with smokers over cats living in a non-smoker’s home. Dogs living in a home with secondhand smoke have a higher risk of nasal tumors. This increase was specifically found among long nosed breeds (like me, Golden Retrievers). Dogs with medium or short noses did not escape, as they showed higher rates for lung cancer! Typically, dogs affected with nasal cancer do not survive more than one year.

Be aware that animals may also pick up discarded butts off the ground and ingest them. This creates a problem with nicotine poisoning, which can be fatal.

Smoking is also a very costly habit. Do you know how many homeless animals could be fed in one year if just one person quit and gave their savings to a shelter or a rescue?
