Yes, it does look like Gizmo has worms! They appear to be roundworms, which can be killed with an OTC deworming treatment called Panacur. You can get Panacur at a pet store or your vet's clinic. It's a three day course of treatment, and Gizmo will need a second dose of it two weeks after the first was given to kill all the worms. He should then be dewormed every three months thereafter.

    That sounds like roundworms, which are common in puppies. You will need to deworm Bella. I recommend Panacur. It's a three day course of treatment, and she will need another course of treatment two weeks after the first ends to kill all the worms. Then she will need one every month until she is six months of age, and after that she should be dewormed once every three months. Best of luck.
