Probably best to ask on the dog board. I used to have collies and they could get a bit out of sorts unless they had a minimum 2 hours a day over the piece. (So when I was on sole walking duties - say on a morning in early January when the rain and sleet were coming down - it required a certain resolution.)
Nothing like having a cat when it's mud and -2 outside. (Although I'll grant you the joy of a country lane on an early summer morning with a hound gambolling beside you.)
Just what cozietoesie said really. Keep the puppy on the lead when you introduce them and take it slowly.
I had 2 17yo cats when I got my puppy. The male cats has since had to be pts - nothing to do with the dog. But my male cat and the puppy formed a strong attachment and would sleep curled against each other. Female cat is more independent generally and just about tolerates the dog.
As long as the cat has places to go where the dog can't get to her it should work. Your cat is still relatively young so should adapt.
I think the secret is to set boundaries for the dog from the beginning, so he knows that he is not allowed to chase her, but she will let him know if he's annoying her.
About the biggest problem I've found is where to put the cat's food bowl. I currently feed my cat on the dining room table, not ideal, but if I put the bowl on the floor the dog creeps across the floor like a panther and dives in and gobbles up the food as soon as poor cat lifts her head.
It is definitely doable. Do post an update to let us know how you get on.
I wouldn't worry about a cat and a retriever living together. A retriever is the sort of dog who should be easily dominated by a feisty cat.
The only initial problem you might have is that young/puppy retrievers are so flipping exuberant, the cat might just get a bit fed up with it trying to eat its tail, do whirligigs in the middle of the sitting room etc so you'd have to provide the cat with a safe place to go to get away from the dog.
Maybe a stairgate (if you have an upstairs) or a doorgate which the dog couldn't get through would be the thing - and leave yummy food and water for the cat somewhere up there. Plus lots of extra TLC for the cat and plenty training for the dog - which you'll need for a retriever anyway. And be round when they're together at the beginning to supervise.
I'm the owner of a beautiful Mackeral tabby girl. Had her as a kitten and she's now 4. She's a law unto herself, comes and goes but can be sooooo affectionate, when she wants. In short, love her to pieces.
I've debated for years on wether to get a dog. As a child we had a golden retriever who ate the arm of the sofa and my mum (I was about 6) said she had to go. I'm 50 now and still want a "Heidi" dog (the retriever). I'm really worried though that my cat might leave home. That's it, really. Any advice? Is it "do-able"? If I don't do it now, ill be too bloody old to walk it!
