My dog had hookworms, but she is on the mend. Will her having had worms make her smaller than she would have been otherwise? She is a little ball of lightning in the shape of a American Pit Bull Terrier, if that helps. Thanks a mint
Mikey, I believe you are speaking of ring worm. The hook worm is actually an intestinal parasite. What makes it dangerous is that it will cause the dog to be anemic. And thus sickly and lethargic. Those mean blood suckers!
So to answer the original question, I don't think it would affect the growth too severely, unless it was a severe long term infestation. The poor pup needs a lot of blood to aid in his growth, but you have treated it, so you pup should be fine.
