I am suspicious that Daxter might have tapeworm, I saw some white strip in his stool 2 days ago and also dried yellow thingy in his bed that is looks like a grain rice in his bed and his butt this morning after he goes poo. So I am taking him to the vet tonight just to make sure.

Do you guys know if tapeworm contagious to other dog if they are living in the same room and sniff each other? I just had my friend's dog stays overnight for 4 days.

How to clean the house if your dog have a tapeworm to prevent it from getting it again. I vacum and wash his bed already with a hot water. But what about carpet or tiles area, should I use clorox and spray all over it to kill the egg?

Help please! Thanks!

MB is exactly right (as usual). Animals get tapeworms from fleas or from eating invested creatures (moles, squirrels, etc). What you saw was definitely a tapeworm. They are little rice grains that joined together make a long, ribbon strip. You need to worm your dog and i would probably treat all of them and treat for fleas. Eleminating fleas will probably take care of the problem, unless your dogs are big hunters. There are several medications your vet can provide for flea preventative. I use one that prevents heartworms and fleas. Good luck
