We all want a healthy pet.... It's hard to get your dreamed about dog and realize it needs special attention and care, and wait for new symptoms to arise for some unknown diseases it may carry. When did it get so complicated? When I was growing up (not that long ago, c'mon...about 15 years or so) it was easy. When you decided you wanted to own a pet, you made sure it got it shots, you took your time to train it and love it. I don't remember anyone I know owning a pet with life-threatening problems. I understand your dilemma... And I won't tell you what to do. You need to come to that decision by yourself, just follow what you think is best for you. As from my experience, I was initially looking for a 'tiny' Yorkie (didn't do my research and didn't know so many things can go wrong with those little ones
). When I got Pepper I wanted him small, around 4 lbs. And it looked he would be. He was 1.6 at 10 weeks and got a very bad reaction to one of the vaccines. I almost lost him, had to be rushed to ER vet for IV. I realized he's dangerously small, and started hoping he'll grow more than those 4 lbs. He did and he's over 3.5 lbs at 4 months and I know he'll grow more still (I'm hoping for 6 lbs or even a little more- that's a good size). Last vaccine didn't have any effect on him -he played the whole day after - and I know it's because he's way bigger and stronger. Those guys are so tiny when regular size, it's just scary with 'runts of the litter'. I personally don't think I could afford a lifelong of worries about a sick pet and a lifelong of expenses that come with it...
