Hello, we are looking for help with our 3 month old puppy. I know he is a puppy but his behavior seems like there is something going on with him. He is a Saint Bernard Coonhound mix. He is constantly biting us whenever we get close to him. We try to discipline him but it seems he gets worse when we do. If we throw him a toy he will start to run after it then turn around and dart right at us and bite us.
If anyone has any advice that would be greatly appreciated, thanks! I have posted pictures and videos below.
