Why does my dog itch constantly?

Itching could be due to a variety of factors such as allergies, rashes, infections, etc. Fleas and ticks are especially prevalent around this time of the year. I would recommend consulting your local veterinarian!

When the vet has ruled out the above reasons, it may be time to check food allergies. I had his done after several rounds of antibiotics, constant itching and my dog smelled like yeast. I requested formal allergy testing from my Vet and when we got back the results it was revealing. I got a little booklet which listed all the food items (five) for my dog AND there was a list of wet and dry dog food brands and "flavors" my dog could eat safely. They also listed treats that were "safe"

I went to the feed store with the brochure and the owner asked what I was looking to spend, and he went through the booklet, told me what he carried, what he could get In quick, and what special orders he could do. We discussed the merits of different foods, and what I hAd already figured out on my dog's flavor preferences.

Within days my dog (adopted from a shelter) stopped smelling like yeast, itching and ate all the new food, and left the other food -so much for "gradually switching him over".

May be it your dog itch constant because of Fleas. As, my dog was also having similar issues. I had consulted the vet doctor, where they said that my dog is having fleas. I had started providing Fleas treatments for my dog since they get outside and inside multiple times per day. On the recommendation of doctor I prefer to use some Fleas removal methods by using some latest generation of Fleas treatments like using sprays. But for safer and effective way to eliminate Fleas, I had hired environmentally sensible http://eastbaypestcontrol.com (Pest control Walnut Creek CA) exterminator, who came over and eradicate Fleas quickly and effectively from our dogs and from geographic areas where they are usually found.
