What dose to give a dog 32 kg?

You did not write what drug you are talking about, so it is difficult to give an answer. Please note, however, that if you are to give your dog a medicine for humans, it is best to ask your veterinarian about the dosage. Not all medicines for animals from the pharmacy will be suitable for certain species at all, so you should not decide to give your dog medicines on their own. In the case of medicines intended for animals, the dosage should be in the leaflet, but - again - if you are not sure what the veterinarian recommended, it is advisable to contact the animal clinic.
