According to vets, a dog can have Benadryl, but only after consulting a professional veterinarian. Benadryl is given to both dogs and cats to eliminate issues such as eye infections, insect bites, insomnia, anxiety, skin irritations and fleas.
Benadryl is medicine made for human beings to help treat allergies and loss of appetite. Before giving it to a dog, a person needs to get the recommended dosage from a vet. Weight is one of the most significant factors used in determining the amount of Benadryl to give to a dog. A person needs to use the drug carefully on dogs suffering from heart disease, hyperthyroidism or bladder disorders.
