Hi, I'm just looking or some advice. Our 13 week old lab x puppy has just puked up a massive pile of live worms. He had his first jabs at the vets on 30th December and the vet gave him a wormer/flea treatment ( I can't remember the name it was one of those that go on the neck). Two weeks after he had his other jabs, and he's due back at the vets on Wednesday for his next flea/worm treatment and a microchip. The vet said he might puke up or poop some worms, I've never seen any in his poo but I thought that if there were going to be any from the last treatment it would have been sooner than now as that was almost four weeks ago. Shall I ring the vet tomorrow and see if we can go in or wait til his appointment on Wednesday? This is the first lot of worms I've seen, does this mean he's got a bad infestation? They were very big and quite a few of them. I feel pretty sick tbh and a worried for my pup! Are there going to be more coming out soon?
