My BT came back from the groomers with a bald spot on his front leg. He has been licking it and it now looks quite sore. DH reckons just getting one of those plastic collar things will do the trick - he is wanting to avoid an unnecessary vets bill. I'm worried because it looks so sore, do you reckon it's worth a trip to the vets (and more likely than bit a 60 quid bill)?
