My dog passed a single white or pink worm in his stool. What is it?

Pet's info: Dog | Great Dane | Male | unneutered | 2 years and 4 months old | 119 lbs

I had seen a pretty large worm in my dogs stool 1 time about a month ago, never saw another one since...until today...today I noticed another worm that seems large but not as large as the first worm. I have never in my life seen anything like this. Usually it's lots of worms and everyone they go to the bathroom. What type of worm would it be if it is just 1 worm once in a while? They are long, round and white, but this last one looked like it was pinkish on one end of it...

Well, first of all, if you actually see a worm in your dog's stool, there are many more in the intestine and it is kind of overcrowded. The white worm may be a tape worm, the pinkish one is likely a round worm. You will need to worm your dog, preferably with Drontal plus or a likewise wormer that contains also Praziquantel to kill any tape worms.
