Hi, looking for a bit of advice! A couple of months ago, we adopted a 9-month-old border collie who has recently started developing a couple of really weird behaviours. I would really like to hear if anyone has experienced something similar. Two things really: firstly, about a month ago he started to refuse to go into the field where we often walk him. He wants to go through the gate, but as soon as we're in the field he pulls to go back out and go home. There is nothing different (that I can see) about the field, he doesn't seem scared, just really doesn't like it anymore. It doesn't really matter as there are other walks, but I can't see why he would suddenly refuse to walk there. The other thing is a bit more concerning - he has become obsessed with a little part of the path to the house. When returning to the house, he will stop there and stand over it with head down, ears back and legs apart, almost zoned out. He won't come when called and tried to nip at my welly when I went up to him. Today, I stroked him while he was there and he snapped at me, not in a friendly way. I've also heard him whining at this patch of ground and circling it. There is nothing there! I'm concerned as it's escalating and I'm not sure that he wouldn't bite (me or someone else) if they touched him when he's in this zone. Any thoughts? Thanks in advance.
