If you are unsure if your yorkie has been treated - VET ASAP ...heartworms are nothing to fool around with - it's a horrible treatment once they get them -
you want her worm free so I think she needs to go see the vet right away - just do everything you can and PLEASE dont rely on others to take care of your dog - YOU are in charge now & she needs medical attention....
Worms just freak me out - and yes they can pass them on to other dogs !!
GOOD LUCK !!! |
