Hello,
Different vets feel differently about the use of cough syrups for dogs. The fact is many vets do recommend Delsym for dogs when they have a cough. Our clinic does incorporate the use of Delsym at the dosage of dogs under 10 pounds get a child's dose and larger breeds get a adult dose. It is non narcotic so it is not toxic to dogs, though it is always advisable to follow your vets recommendation so I can not tell you to go against what you vet recommends.
