Yeah, I know...worryin
g is what we mom's do best.
I'm really sorry to worry you more, and I sympathize with the idea of a pg mommy hauling 3 kids and 1 humongous puppy to the vet. It's enough to give me a headache just thinking about it! LOL It's just that it doesn't sound like the rest is improving his limp or the swelling, loss of appetite and maybe some lethergy, too?
It just doesn't sound right to me. Maybe he's just feeling sore from a sprain or strain so he's just staying still a lot, and I really hope that is what it is, but personally I just wouldn't want to risk it. BTW, x-rays aren't as horribly expensive as they might seem. Around here, if they can get a clear x-ray w/o sedating the dog, it's about $40 for the first x-ray and around $10 for each additional x-ray taken at the same time. I'm sure that it varies a lot from place to place, but that might give you a general idea. Our first vet never even mentioned the idea of x-raying, much less the approx. cost, or we would've opted for it sooner. Personally, now if anyone here starts to limp we'll be having a quick x-ray done just to be sure.
