Our pup is now 13 weeks, is a very happy chap, sleeps through the night in his crate, is coming on well in training, but can get very distracted (even from eating his meals) when he just has to scratch, nibble and lick himself. It’s getting to the point of him having patches where his fur is quite sparse, for example, in his armpits and along his legs. Wondering if it’s an allergy, either to a foodstuff or pollen (we have an area of longish grass in the garden which he loves running through). His kibble says it’s grain-free, but we have been giving him Waggs biscuits as one of his treats, which we are now going to hold back on in case it’s a grain intolerance. Anything else we should try? He has had worming, flea, mite treatment etc and there is no sign of any parasite.
