We have had our 14 week old Cocker for just over 6 weeks now and all in all he has settled in really well. He has pretty much mastered toileting outside, sleeps through at night and follows basic commands. My only real issue at the minute is he is really hyper of an evening. We take him out for his 15 minutes but when he comes back he goes nuts barking at us and bombing round the house and biting. I take him for his evening walk around 7pm. Am I taking him out too late? He normally calms down eventually and then rests for the evening but is there anyway of preventing this behaviour or at least shortening the period of time he is hyper for. Any advice gratefully received. Thanks.
