Though these issues are seen far less often with Beagles, all are possible causes of severe and compulsive paw licking and/or chewing.
Parasites
– Though mites and fleas are usually a full-body issue, this can start on the paws. Ticks, on the other hand, are localized and would often involve just one paw.
With mites, there is usually hair loss, inflammation, and oily skin; this often will progress from the paws over to other areas of the body. And, though nearly microscopic, mites may be visible on close inspection. Mites diagnosed via a skin scraping and treated with topical anti-parasitic medications.
With fleas, there is severe itching, often quickly spreading to other parts of the body. It’s not easy to see fleas since they are super-fast and jump out of the way when hair is parted, but their droppings (tiny black spots) may be visible. Treatment for fleas must involve both topical treatment for a dog and treating the house.
Ticks
bury their head into the skin, but the body will be seen. Depending on the type of tick and how much blood it has ingested, these can range in size from 1/8 to 1/2 long. Ticks should be removed asap; it usually takes 36 to 48 hours for disease, including Lyme disease, to be transmitted.
If steps such as offering ‘stay busy’ toys, playing music or leaving on certain TV shows, and having a dog walker break up the day, etc. are not working, prescribed anti-anxiety medication may be needed.
