Can a puppy die from geting to much wormer?
Yes a pup can die from giving it wormer if you give like tripple the normal amount called for but for the most part it is hard to overdose a dog on over the counter wormer. If the puppie is infested with worms it will die if you give it wormer because there are certian worms (hook) that attach to the intestine and when they are all removed or killed at once the intestine bleeds where the worm was attached and the pup will die.
