I understand you feeling like you're being jumped on, but it's not the case. At this point it is an issue of safety and money. The vet is either going to say "We'll see how it goes and do an ultrasound when the time comes to verify size." or "We need to spay right now." Yorkies have issues giving birth due to their size, it's just the way it works. Stressing a girl of this breed even more by using a substantially larger male is an issue. When you're 8lbs, 15lbs is almost TWICE your size.
If your vet does let the pregnancy progress and do the ultrasound to check for pup size, if they're too big he will have to spay the mom. Then you have puppies that can probably hear and smell and squeak not being given a chance at life, a very sad mom, and a VERY expensive vet bill. Even if she does carry the pups to term, if they're by that eskie she'll need a C-section. There's no guarantee which male did the job until you ultrasound for size, or they're born. If she has a c-section, she probably shouldn't be bred again. Either way, you're looking at spaying her. There's really not many other options a vet can give you than that. I know you don't want advice. This isn't advice, it's just logical reasoning. I know you'll listen to what the vet tells you because you're a good mom, we're all just giving you a heads up. |
