I have a 2 1/2 year old labador mix that recently has been acting weird, we recently had a 7 month old husky puppy pass away from parvo I was heartbroken and they were really close. My lab won't eat but will drink ,her BM are kind of soft not runny though, she puked 2 times like 3 days ago and hasn't puked since then could she have caught parvo being older? She was our rescue dog about a year ago and we asumed she got her shots and now we have our fingers crossed. Do you think it could be depresstion from the other puppy passing away?
