Our border terrier is two in the summer, and is eager to please and very affectionate. But he is also extremely fast and fit, and loves to chase; worst of all, he chases cars.
Atm, obviously, we keep him on a lead more or less all the time. But even in the middle of the countryside, he'll take off after squirrels or birds and then we worry that he'll end up near a road. His energy is very high, so he does need to run.
I constantly practise recall with him, and he is improving - ie he will often come to me instead of going after a squirrel he's seen. Often, however, not always. I feel his behaviour is worsened by the fact that we habitually let him out into the garden after dusk, and he spends his time rushing around on a high, going after everything that moves. Do you think it would help if we simply ban this night-time hunting? I think he could still be allowed out into the garden during the day, because he seems much calmer then.
