Dog scratching and biting.

Dr. Marie replied:

At this time of year the most common reason for a dog to suddenly be itchy is definitely fleas.

Fleas can cause a dog to be itchy anywhere but here is the most common area that is affected:



It is really common for a dog to have fleas and for you not to be able to see anything. Sometimes you can see flea dirt. This looks like little black flecks. If you take a piece of this dirt and put it on a paper towel and add some water to it you should get it to make a little red smear.

However, if your dog is itchy above the tail then even if I didn't see flea dirt I would treat for fleas.

Do not buy a flea product from the pet store. They don't work. This has been the worst year I have ever seen for fleas. My thought is that the use of pet store products has created resistance amongst fleas.

These are the products that I find work well...Frontline, Advantage, or Revolution.

If the dog is itchy on the feet then this could be due to allergies. Most dogs with allergies do need to be on medication prescribed by a vet.
