My dogs are itching and have bumps. How to tell if it's fleas or lice?
Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Hunny and your other dog. Fleas can be difficult to find but the easiest way is to get them to roll onto their backs and look in the thinner haired areas of the body. You can also purchase a flea comb which can trap flea dirt (small pieces of flea poop/digested blood) that looks like pepper or it traps adult fleas and other stages if present. Another method is brushing or petting the hair in the opposite direction of hair growth and look right down onto the skin level. Fleas like to hang out around the rear part of the dog near the tail and rump. Examine those areas closely. If you find some black pepper looking objects, place those on a paper towel and wet it. If the spots turn reddish than that is flea dirt. I haven't seen cases of lice in dogs but cats tend to have more lice especially ones that are wild or community cats. Dogs can also get ticks and mites which your veterinarian can help to identify. I would go to your vet and let them evaluate Hunny and make recommendations based on the physical exam. Flea/tick products vary widely depending on what the owner likes, geography, what your veterinarian likes, etc. They can direct you to the best products. Also, we are in a high allergy season in late summer with weed pollens. Dogs like people can be allergic but if both dogs are itching, they leads one to assume external parasites like you mentioned and I discussed. Good luck with Hunny.
