Also use petshed here. I absolutely refuse to dick around with my dog vet for things as basic as dewormer. They won't even sell non prescriptiond dewormer anymore without seeing the dog for an exam and a fecal. Ridiculous.
My small animal vet will not call in prescriptions. The only way I can get heartworm preventative is directly from his practice. I really like this vet and his prices are reasonable, but I really wish I could buy me pets' medicines online.
You can. You just have to buy them online from Australia or Canada.
