Questionhi i have recently had a staffordshire bull terrier from a very irresponsible owner and he is a little under weight and they don't now when he was last wormed will it harm him if i worm him anyway
AnswerHi Kerry-
It depends on how under weight he is- if he is just a little under weight, I would go ahead and worm him, but if he is emaciated or rail thin, I would suggest holding off until he has a bit of weight on him, or consult your vet first.
Thanks for rescuing!
