Friend has a British bull dog, it's had something done to its eyes which means it has to have drops in every morning for the rest of its life! He was telling me they are charging him £25 a pop for these drops once a month plus whatever to see the dog, I casually said have you searched the net for them as a lot of stuff vets use like that is for humans as well.
He went home and looked found a bottle of the drops twice the price for £3! He had been buying them drops for 2 years.
So probably yes but what do know. I only deal with animals that aren't breathing anymore.
