We got a rescue dog, vet told us he has a lot of border collie in him, he's about 1 and a half years old. The problem: it seems as if he can't get tired or get calm, it happens everyday. We've had him for 4 months.
First we started to go on short walks, all OK, he urinates and defecates, we get home and he turns into a completely different dog: he starts zooming, biting (me and my wife), biting his bed and his pillows, pulling from his leash when we go upstairs.
When we noticed this we thought 'Hey, maybe he needs more exercise', so we started taking him to a park where is a designated space for dogs and their owners, so they can play there; he runs, he plays, he urinates and defecates, we walk back home, all OK, we get home and he turns into a completely different dog: he starts zooming, biting (me and my wife), biting his bed and his pillows (this lasts for about 20 to 30 minutes until he lies in the floor).
So we turned to a 'trainer' who told us to use a spray and water to correct bad behaviour, it worked for like a month, one day he got the spray thingy and destroyed it as an act of rebellion. So we decided not to do it anymore.
We got a bike, so we take him on bike rides so that he gets a little bit more tired than just the park, sometimes we take him to the park on the bikes for extra exercise. Nothing, he comes back at home and it's the same behaviour.
This makes me feel betrayed because I feel like I've been doing my best, but he just keeps insisting on behaving like that, sometimes he bites really hard, he's even bite my mom once.
I've tried positive training with treats and small bits of sausage (he loves those), but when I run out of treats, he forgets it and goes back to bad dog mode.
I don't know, or, we don't know what else to do. It makes me feel sad because I've even thought of giving it back and forget it, but I don't want to give up on him, so I come to you in ask for help.
Update: As of today my dog has been behaving so much better when it comes to coming back home. As I said, I started day 0 with giving him treats after making him stop biting the leash. Also give treats when going up the stairs to put his attention on going up rather than biting the leash or us.
Yesterday it was rainy so we couldn't go to the park. Caressing him and giving him treats when we noted his anxiousness seemed to work enough.
We having been riding on the bike lately as it seems the park is enough now, he even started to play with his own ball and comes back to us, he also responds to the call faster. It's been about 2 weeks when we started feeling we had another dog, maybe it's part of him growing up but it seems he behaves better now. Thanks. I'll keep updating like this!
P.S.: I forgot to mention our vet told us that he's allergic to mostly everything. He scratches himself A LOT, he's even hurt himself badly once (we treated that). Our Vet recommended us some shots of CYTOPOINT to treat his skin allergy. We recently heard by an animal behaviourist that these allergic dogs are the ones that present more behaviour difficulties.
