My dog has roundworms. Can I switch dewormer brands safely?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 11 months and 21 days old | 32 lbs

hi, I have a medium sized shepherd-terrier mix, he weighs about 30 lbs and is a year old. We discovered roundworms in his feces yesterday, and administered what was left of his worm medication from when he was a puppy, planning to buy more. However the local stores arent carrying the same brand we gave him yesterday. Is it okay to purchase and administer a different brand of dewormer for his last 1.5 doses? Ive attached photos of the brand weve administered 1.5 doses of.

It's fine to administer Atlas a different brand of deworming treatment, and I recommend giving him Panacur. It's an excellent deworming that you can get OTC, and it kills roundworms, hookworms, and whipworms :-)
