Chewing Leg / Hair Loss?

My nearly 5 month old cav, Alice, has been chewing on her leg some recently and tonight I noticed that she has a patch of hiar loss where she has been chewing. Does anyone else have this problem with their cav and if so what was the cause? Could it be allergies? She doesn't seem to have any other issues. No excessive scratching. I haven't really seen her chewing her leg a lot, just occasionally, but now with the hair loss I am kind of concerned. Since we have a herd o'dogs I try to avoid going to the vet unless we absolutely have to! Thanks in advance for any advice!

It could be a hot spot,but i would take her to the vet just to get it checked out.

My Golden used to chew his legs and pull out his hair due to stress when he was younger. I agree though - a vet is the best one to diagnose.

Maybe even a phonecall to your vet and get his opinion

You definitely need to see the vet. If this is so irritating to the point of stripping hair off the leg, then she is very aggravated by something, be it a severe allergy, dermatitis, pain, or whatever may be causing this reaction.

Winston did this too and his anal glands were infected.
