The rule is 1mg/1lb. So for 130lbs, you could give 130mgs. But, not necessarily so much.
25mg should be perfectly fine. You can give him that every 8 hours.
an 8 lb. dog needs 16 mg of Benadryl, so you can give it one teaspoon ofchildren's benadryl which has 12.5 mg. make sure it is regular benadryl and doesn't contain acetaminophen (to check, look at the active ingredients in the box or bottle).
Is this under a vets supervision? I would call the vet.vet has prescribed 2x 5mg tablets twice a day for a bichon frize 6.4kilo.
Dogs should not be given human medicine.
Never give human medicines to an animal. Many human medicines cause great harm to animals. See a vet.
The amount of Benedryl given is dependent on weight, not age. I give my 70 lb lab 1 tablet. talk to you vet about specific dosages for your dog.
Hornswoggle is 130 lb.
goku is about 130 to 136 lb
I am a registered Vet assistant, and have been working at a vet clinic for some time. WE give liquid and pill form benadryl quite often to dogs. The rule of thumb is 1mg per pound. For example: a 25lb dog can take 25mg of benadryl. I read on a veterinarian hospital page that you were NOT supposed to give the liquid form of benadryl to dogs.
Age is not a factor when giving Benadryl to dogs. The factor is the weight of the dog. The rule is that your dog should have no more than 1mg (milligram) of Benadryl per lb (pound) of weight. So if your dog is 5lbs, that would be no more than 5mg. You should consult a vet first, however, as it is possible for dogs to be allergic to the medication.
It depends on the dosage of Benadryl (Diphenhydramine Hydrochloride (HCL)). The recommended dosage is 1-2mg per lb of the dog. So your 20lb pug would need approximately 20-40mg. The standard Benadryl tablet is 25mg. So give your dog roughly 1-1.5 Benadryl tablets every 8-12 hours as needed for symptoms.
