I live in New Zealand and it has come to my attention that there is a female 2 or 3 year old newfie that the owner wants to sell, as she has 3 of them and they are too much. I have not seen the dog yet. She is asking 1000.00 for it and puppies are 3k here. The dog has not been in the house and is not house trained. Nor do I know if it gets along with cats, as I have two white cats, one is deaf, and NONE are allowed outside. What are the chances of housetraining this dog and also introducing it to cats?
