> Lottie although she is young is doing well with her training but im not sure how to train her to leave the cat alone - he is an antisocial cat!
Reward her for
not pestering the cat.
When I got Buster, my cat HATED him. she spent the first few weeks hiding away and then when she finaly could stand being in the same room as him, she'd run away if he went near, or she'd attack him. Buster found it all great fun - fun to chase if she ran or a brill rough game if she battered him!
I would reward him for improvements in his behaviour. It was a slow process, but bit by bit he learnt to leave the cat alone. Busters highest value reward is food, so he got a food reward for steps in the right direction. Use which ever your pup finds most rewarding (your pup may prefer praise or a toy etc.)
As well as Buster learning how he should behave around the cat, the cat also learnt how to behave around Buster - she has realised that if she ignores him (he will poke her with his nose to try to get her to 'play'), he'll most likely get bored of her and leave her alone. He also has leart that pushing the cats tollerance level too much she'll let him know he's over stepped the mark (he has the scars up his nostrills to testify to this

). However, not all cats will learn to ignore the dog when it's being a pain.
As others have said a cat scratch to the eye can be serious, my sisters boxer pup had to have her eye removed at 10 weeks old due to a cat scratch, just be aware of this.
Lots of time, patience, supervision & training and things can be really good. You just have to remember that pup finds the cat lots of fun, so in order for pup to want to leave the cat alone you need to provide a very nice alternative to 'cat-fun' , ie. high value rewards.
Busters 'cat training' has also been extended to include any cat that enter the garden or that we may happen accross while out & about. Only today we were walking along a pavement, there was a cat sat either side of the pavement facing each other (LOL, they were staring each other out), we walked past, Buster on a slack lead, he did have a happy faceon and was wagging his tail (he loves cats!), but he didn't need reminding to leave them alone :)
When ever I am roasting a chicken, you usually find the teeny, tiny cat sat next to huge Buster, waiting for morsels. Mitsy (cat) will get her little bit first while Buster waits for his bit. :)
