It sounds to me like your vet maybe gave you Panacur, in which case, you should be good to go for awhile as it's a great broad spectrum product.
Do realize your pup CAN pick up parasites anywhere, so if I were you, I'd have another fecal check done at least when you get your final shot.
Glad you got to the bottom of that on the face! Now just have fun...

Thanks Windy. Think you are correct regarding panacur. Vet definitely wants another stool sample bout 2 -3 weeks. Going there anyway for second round of shots. (12 weeks) But if there are no reprocussions I may just ask him for 1 more round of panacur in case any dormant eggs left. So far so good. I did notice a lot of the little white dots on face where also locations where whiskers come out. If a yellow I prob wouldn't have noticed. But whew........definitely work!
