I'll try to be as thorough as possible so this may end up being a bit long but any help would be appreciated.
My husband and I have a male beagle who is almost 4 years old. We've had him since a puppy and during that time we cannot rub or touch his belly, he doesn't seem to even liked being pet and has always been aggressive. We handled him a lot when he was a puppy so him not liking to be pet I don't think has anything to do with lack of human contact. He has a ton of energy and we walk him 2 miles a day (one mile twice a day) and play fetch the ball with him quite a but. He is also neutered and has gone through the basic canine obedience class.
I admit that when we first got him, we'd punish his bad behavior by giving him a spanking on the rear. Nothing hard but enough to get his attention. After taking him to class (he was 6 months old when he started class), we learned that is not a good way to punish a dog. Instead, we will yell really loud at him to simulate barking. Or sometimes, we have to hold him to the floor, which sometimes is the only way to get him to calm down without him actually biting us.
There have been many occasions where he will get aggressive with myself or my husband. Most of the time he will get excited while playing and snap and growl at us if we try to pet his side while playing. When that happens, we will 'bark' at him and that often calms him enough. He will also growl and bare his teeth at us when we try to make him to something that he doesn't want. For example, if he got up on the couch and we tell him to get off and he doesn't, if we were to try to pull him off, he'll bare his teeth and possible snap at us. Anytime we try to physically try to move him, he gets nasty.
There also have been instances when he gets downright viscious, very aggressive, and scary. It doesn't happen often but it's happened enough that we are getting a bit scared of our dog. When it's happened in the past, we've been quick enough to not get caught in the crossfire of his teeth but last night, my husband got bitten by him.
Each night before we go to bed, my husband takes him out on his leash to pee. Usually he'll go right to the door and there is no problem. Last night, he did not respond when my husband told him it was time to go out and pee. Our dog was sleeping in his chair and my husband tilted it enough so our dog had to get out of the chair. My husband then bent down and put the leash on him and as he pulled his hand away, our dog got extremely viscious and actually bit my husband.
We don't know what to do. We don't know what we are doing wrong. We don't know if there is anyway we correct this behavior. We are afraid he will do it again and if he does, we will probably opt to have him put down. Is it us or is it the dog or a combo of the two? Please, can anyone help us?
