My beagle is showing aggression

Question
Hi there.My beagle is around 9 weeks old.Hes a male.The first two weeks I bought him,his behavior is still ok.He learns how to sit and comes when I call his name.He is also quite attentive.But last week starting,he starts showing aggression,I guess it is because I often lock him in the cage.Most of the time he spends his time in the cage because if I release him,he starts to ruin everything in my yard.But I often come out to talk wif him and play wif him when he's in the cage.But everyday I will let him out for an hour,and he likes to bite up my grass and eat it.And starting from last weeks,when I call him to me,he starting to "hug" my legs and scratch and bite (lightly not really bite until bleeding ,just little scratch),and he knows I'm angry and want to take him back to his cage,he starts to run run run to avoid me.What should I do?

Answer
In all honesty the best thing would be to find him another home. No dog, let alone a beagle should spend that much time in a cage, it is not healthy or emotionally good for him. I am sorry but this is not the way to treat your dog. At nine weeks he is a tiny little baby. He shouldnt have been released from his litter before a minimum of 8 weeks and preferable is 12 weeks so that he can be properly socialized within his litter. Lack of this can cause aggression and behavior problems and then locking him in a cage is even morre likely to cause agression and issues. This puppy needs constnat handling and love and affection. His eating things and biting at things is normal behavior. He will notlearn to do things right locked in a cage.
