Dog Tenia or tapeworm

Nematodes or roundworms are mostly a problem of female dogs and puppies. On the contrary, tenias are mainly found in adult male dogs. You will, perhaps, start to suspect their presence if your dog suddenly loses weight and/or drags himself on his hind legs. You will only certainly know once you see mature segments of tenia in his feces. Tenias look like little slugs, they move about slowly and are angled if observed really well. They are not as easily detected as roundworms. The way they get infested is by contaged fleas.
