Hi everyone. Recently, my puppy (a beagle) has been scratching behind the ears, and sometimes nibbling on its thighs quite frequently. She's 9wks old. I've checked her thoroughly and could not find anything unusual on her skin. There are no ticks or fleas, and there are no visible skin problems or anything like that. I've also checked her ears to make sure there's no infection building up. She's wearing a collar all the time, but I don't think that could be the problem. I'm planning to ask my vet though, but I was wondering whether any of you have faced similar problems before?
