our pup vomited this morning and we noticed something that looks like worms but we are not sure. can they throw up worms?
Yes they can when they have a very bad worm infestation. When was she wormed last time? You need to do this again as soon as possible.
Take her to the vet, she might need special treatment.
Nemex-2 is what my vet recommended for my cat. Dr. Fosters-Smith has a generic brand that's a lot cheaper. Dogs & cats can use it, although it is branded for dogs. My vet uses it for both.
