Even if there was some freaky accident at the cannery and somehow there were worms in the tripe and they survived canning , they still would not infect your dog. Dogs don’t get tapeworms that way, and I’m really not sure that they could get any other kind of worm that way either. I do know that every type of worm has to be ingested at the right life stage and tapeworms are gotten in two ways. One type is from eating fleas and they can take months to show up in the stool. Another type comes from eating lizards, and you may never see segments with them. Other worms have to go through snails or they live in the soil for a while and are picked up on the grass and ingested when the dog licks itself.
