hi everyone I am really worried about my 14 week old puppy. Yesterday he was unwell he has no energy, and when you pick him up he cries like hes in pain. I got wormer today for him as the girl said he sounded like he had worms. Can anyone please advise me what it is? Has this happened to anyones puppy before? Also he is very unsteady on his feet. I would be grateful of any advice

can anyone tell me the symptoms if a puppy has worms?
