Thanks Pinkbike. I'll have a look for that. We're going up to the vets in about half and hour. They usually have details of dog training classes as I think Max would benefit from that (and us too). He did try and chase my cat last night (the old, crippled cat who lives in our bedroom) and was scolded for it ("No!!! Bad boy!!!). He knew he'd done wrong and lay down quickly. Our last dog was the same initially with our cats but learnt very quickly not to chase our cats. She also learned the hard way when she went too close to one of our cats - and got her nose shredded. She soon learned chasing cats wasn't a good idea and for years the cats used to curl up with her, especially in winter. Us humans couldn't get anywhere near the fireplace. The furkids were all curled up in front of it
