I love my 4 month old beagle but i need alot of help with him. Constant biting occurs from him and it hurts. You can not pet him without him trying to bit you. If I put a toy in his mouth he will bit it for 2 sec then go for my hands or any body part that he can get too. I yell NO!! and it doesnt work, please help me. Another problem is he keeps attacking my cat and dragging him across the floor or going for his neck. I can not leave them alone. I yell at him break them up but nothing works. He also has just learned to get into my fridge. He opens it up and eats all my food. I need to stop this behavior as well. CAN SOMEONE PLEASE GIVE ME TIPS. IVE BEEN WORKING WITH HIM SINCE I GOT HIM AT 6 WEEKS OLD BUT HE DOES NOT RESPOND.
