WOw poor pup, she was almost full.
Yup the vet should have given you I believe 4 months worth of worming.
I'm guessing they gave you Interceptor?
When I had brought Riot home, he was sick the first few days because he had roundworm. But it cleared right out of his system after the first batch of pills were given to him.
Just keep on the pills that your vet gave you and then inquire about a monthly thing for your pup.
