I live in London and own a Weimaraner cross dog - looks like a black
Weimaraner. He's a beloved pet and I'd like to get a puppy or two from
him before he's too old. I can't find anyone with a cross-breed bitch
willing to breed. Ideally, it would be a similarly smooth-coated bitch
- a Great Dane, Mastiff, Weimaraner, something like that. I'd keep a
puppy or two and the owner of the bitch would sell the others. I'd be
willing to pay a lot of money (Around £800) if I can find the right
one. Can anyone provide details of someone willing to do this?

Save your money. There are plenty of homeless pets who need a home and
much of your dog's good nature is due to your good environment, care,
and training. Hoping the offspring are similarly good dogs is a
crapshoot; just look at the variety of behaviour exhibited by the
offspring of cloned animals.

hi I am 13 and i have had the same problem with a hamster. You can
find animal shelters that give away animal, becaful, some are very
expencive and some places won't let you breed the pet.

PS if you ever have puppies take good care of them!
