They grow so fast
If they HAD it how long did it take to get a rid of? If they HAVE it how long has it been?
I think it has a hard time really getting going in adult dogs unless they're immuno-compromised in some way. Gus got it over and over and over, and then boom, with adulthood, he never had a problem again. I'm not saying healthy adult dogs can't get it, but the symptoms really seem to affect puppies more than anything else.I have never had it in any of my dogs (5 goldens now) , but the area I live in was flagged on premium lists as giardia hot-spots so perhaps my dogs develop an immunity to it? They are in the woods most days ....
