Hi my name is Diana and I just got a puppy...he is 4 months and about 7 lbs...he is the cutest thing ever! I wanted to know which kind of kennel or crate people mostly preferred for their puppies. Like a plastic crate or a wire one. I found a really nice plastic one with a door on the top and one on the side so he can stick his head out the top in the car if he wants! Let me know any suggestions PLEASE! also, the breeder said she doesn't think he will get any bigger than the 7 lbs. Does this sound right?
