Hi! Our labrador Charlie is constantly itching/biting himself, despite no evidence of fleas. I've read that there are other causes of itching and was wondering if anyone could help before I definitely need to take him to the vet. I'll explain a bit more on why we think 'stress' could be causing his itching, and if I'm correct, what is the best way to 'de-stress' Charlie. 3 weeks ago my fiance was taken into hospital with pregnancy induced hypertension and for 8 days I was in an out of the house between hospital visits, during this time Charlie was looked after by a family friend and my sister. After these 8 days of frantic trips to the hospital and back, we brought home our son Isaac. Charlie has been brilliant since we brought Isaac home, he's been interested in him and has shown him a lot of affection but his itching/biting has continued and recently it's gotten worse. I've checked him for fleas and only a week ago he had his flea treatment. We also have 3 cats who sleep in the same places Charlie sleeps in, they have been checked for fleas and are clean too. If it's allergies, how do we determine what the allergy is?
