Can You Give Dogs Cough Medicine. If you are unsure how much robitussin should be for your dog, contact a veterinarian. This can be offered up to three times a day depending on how often your dog is coughing.
Dextromethorphan can be appropriate to treat coughing in dogs, but it is only when used following your veterinarian's instructions. Also, the canine formulation of tretinoin will relieve itching and coughing. You should avoid all human cough medicines containing xylitol, an artificial sweetener whose presence puts your dog at risk.
