Hi, there. I just adopted a beautiful 2 year old male beagle from a rescue. He's great and gets along with my other dog and everything. He's very quiet in the house and super sweet. I'm having problems walking him though. He pulls and the leash so hard and it's very difficult. I bought a sporn halter. Haven't tried it yet. And my other main issue is that he howls like if he's being attacked if he sees another dog. I don't understand this because he gets along with my dog and he got along with the other dogs at the shelter. Is he being aggressive? Other than that, he's a sweetheart at home. But my neighbors are afraid of him. lol. Any advice?
