Newfoundland dog breed
Me personally I am against breeding animals since there are so many in the world who get euthanized every day. My motto concerning animals is "Don't Breed the Bred" witch simply means once the dog has been bred once you shouldn't breed the dog again. But if you still wanna breed your dog or your just curious i say don't breed it more than 2 times a year give the poor dog a break!!! But if all you care about is making money go ahead and breed the dog as much as you want. But please remember my motto concerning animals "Don't Breed the Bred!"
No dog. Geckos are not known to like animals bigger than they are. Bigger animals can eat them.

If you are looking for a particular breed, google the breed name and your state. It will show you all the breeders that have online sites and the dogs they have available. That is how I found the breeder I bought my Collie from. If you want a dog from a rescue group, check petfinder.com. They will show you all the available animals for adoption in your area, by breed.
