I need alot of help with my 7 month old beagle. He is vicious. I come home from work around 6 and as soon as i get in the door he is jumping all over me, tail going crazy. Hes happy to see me. So i let him outside to do his thing. When he comes back in i give him some dinner. After that all hell breaks loose. I try to sit down and pet him, i cant he bites me very hard the same with my other roommates. I hit him on the noise and say NO! The bitting continues. I pin him down on his back and say NO! he wiggles and screams and still is trying to bite me. I let him up after a little while of holding him on his back. I walk away from him he comes with me and continues to bit my hands. I have tried giving him time out in his crate, walking away from him spraying him with water in the face but nothing is working. He acts like a pit bull. I do not want to get rid of him but it is coming down to it. The bitting is all the time. You can not pet him without him locking onto your hand and bitting extremely hard. If someone comes over the house he will be nice to them for 5 min and likc them but after that he starts to attack. SOMEONE PLEASE HELP ME
