So I assume then you'll have both his and hers hips xrayed for hip dysplasia? You're also going to check for any heart defects as well?I don't plan on going into this uninformed.
I will find out all I need to do first.
I think your dogs are adorable, but you're breeding them for the wrong reasons. I hope you realize a lot of pugs have problems birthing, many have puppies by c-section [although not as common as in Bulldogs, which is a common thing]. Also it's quite common for the moms to not be so motherly. We've had 3 clients at our clinic whose pug mommy's wanted nothing to do with the babies. The first two litters, they only had 2-3 pups so not a big deal, but the last one had 5 puppies and she had to bottle feed all of them round clock. This is all providing she doesn't have complications and not even make it through the birth.
I'm not trying to be nasty, just being honest. If you were breeding quality dogs, to improve the breed, and to bring out better dogs for the better of the breed, that's one thing. But breeding dogs because you can is really quite pointless. The 3-5 puppies your dog has is taking the homes of 3-5 shelter dogs who will be euthanized, or even 3-5 pugs in Pug RESCUES because nobody wanted them.
