I got my puppy from a pet store about 4 months ago. (I know I know, I said I would never get a dog from a pet store, I got suckered in...) and I feel like im paying for it every day. My dog has had chronic giardia that I can't seem to get rid of..she is on her 5th or 6th round of treatment for it. also had roundworms once in there but I never saw any. I am at my wits end with this and I feel so bad for her, she seems to feel fine, but she can't be around any other dogs and she is VERY dog oriented! Anyway...today I saw tiny whitish worm things crawling in the poop, I came in to get a bag and picked it up right away, it was covered with flies, but they couldn't hatch maggots that quick. It wasn't as big as rice, so I don't think it's tapeworm...I actually cried for like a half hour! I have never been so stressed! She has been on panacur for 5 days now, how could she have ANYTHING!!!!! I don't know what to do I just needed to vent. Has anyone had success with Koccifree,...im gonna put her on it a week after she finishes the Panacur. I just feel like my poor puppy is never going to be free of worms and parasites...and I worry about her longterm health with all this! Am I being overly concerned?
