I'm starting to feel like all the training I put into Thor has somehow undone itself, in spite of what I believe to be is consistency.
Recently he's started having accidents in the bathroom, trying to eat/chew anything in site/grasp, and even starting to nip when I try to take things away that he shouldn't have.
I'll admit he hasn't been getting his usual walks because its gotten a bit colder out, like below zero, but we have been playing a lot of indoor fetch.
I don't know why he's had this sudden destructive behavior, in spite of getting him a plethora of new toys less than a month ago because I thought he was having some separation anxiety.
I'm at a total loss and now sure what to do next...I'm worried he's going to get into something he shouldn't and end up sick, or worse
Any suggestions, or retraining tips would be warmly welcomed. Im starting to feel defeated....
