Is this a canine worm in feces?

These sound like tapeworm segments. Tapeworms shed eggs intermittently so your vet might not have seen them on the fecal exam at your Golden's last health check-up. There are two main species of tapeworms - one is from fleas and one is from small mammals (rabbits, etc.). While it is not an emergency, you should get him de-wormed ASAP. There are no specific preventatives for these worms but due to the infestation sources, keeping him flea free and away from small mammals should help keep him tapeworm free.

My guess would be roundworms. Here is what they look like: http://www.wvhumane.com/parasites/roundworms.jpg. Roundworms are the most common worm found in dogs and cats. I don't think it's tapeworms because tapeworms are segmented and they look like rice when seen in feces. Hookworms and whipworms are much smaller.

I would not wait long to take the dog to the vet for treatment, although waiting until Monday is probably alright.

Roundworms can be transmitted in a number of ways. If another dog went to the bathroom in your yard, and that dog's feces had roundworm eggs, your dog could get worms just by coming into contact with the feces and then licking himself. Generally, the heartworm prevention you use will also prevent intestinal parasites, so you might want to think about switching to another product. Make sure you always give heartworm preventatives with a meal - that helps it to fully digest. I use Sentinel with my dog, and she never has any problems.

Assuming you mean tapeworms specifically, because those are the ones they get from fleas, then could you have a neighbor's cat, a local raccoon, or whatever, using the bathroom in your yard, that your dog may be ingesting? Or could your dog possibly be one of those re-infecting himself by ingesting his own feces, just missing the worming cycle each time? Remember only tapeworms come from fleas - any other type of worms could be from many other locations. Good luck Vintage Collies

Just take a stool sample to the vet to have it tested so the vet can prescribe the correct wormer! Not that big a deal, just get it taken care of. Dogs pick up worms all the time, that's why you get a fecal test done every year during their physical.

If your dog is having diarrhea, cause this could possibly whip-worm. I would take your dog to your veterinarian because whenever your dog is having worms, it is important to have it checked out before it becomes serious. And yes, worms don't always come out in the feces. I would definitely take your dog in to be checked. Best of luck for you and him:)

Sounds like possible tape worms. Get him to the vet asap!

Your dog has worms...TAKE HIM TO THE VET.
