Dachshunds

I'm having some major problems with my dog. Nugget is a 3 year old male long haired Dachshund. Just about a month ago Nugget started to growl at me when I came close to him and he has tried to bite a couple times as well. It's weird though because he now follows my boyfriend around everywhere he goes. Its as if Nugget has given Jason my place. He growls at me but runs to Jason wagging his tail so eager to see him. He won't let me touch him. I'm really upset about this because Nugget is just about one of my favorite things. If you have any suggestions I would really really appreciate it. I'm desperate to get him back to how we use to be.

Maybe you should just win him back, by taking him for walks, Im shure
that he would appreciate that. Take him with you when you have to go to the store.
