1 mg per 2 lbs of weight
In clinical trials with dogs they used 1mg of zyrtec per 2 pounds of dog. So a 20 pound dog can take 10mg although with my 18 pound shiba the vet recommended 5mg. I would err on the lower dose.
1cc per 7 pounds of dog.
6 to 9 pounds
For dogs, the typical dose of Zyrtec (cetirizine) is about 0.5 mg per pound of body weight. Therefore, for a 30-pound dog, the dose would be approximately 15 mg. It is important to consult with a veterinarian before administering any medication to ensure safety and appropriate dosing. Additionally, Zyrtec is usually given once daily.
one milligram per pound.
Ask a vet before you do anything!!
A dog should be give only regular strength Benadryl. For a small dog, it' probably easier to give it the liquid children's formula. The standard dose is one milligram for every pound given twice daily. So for your 14 pound dog, give 12-14 milligrams, twice a day. (If the lesser dose works, all the better!)
3 to 5 mg per pound. That would be 120mg to 200mg.
This question should be asked of your veterinarian - you can probably call over to the clinic and ask rather than make an appointment. Unfortunately, trying to get human formulations of diphenhydramine (the drug in Benadryl) into a small enough dosage to be safe for a six pound dog is very difficult.
1 mg per kilogram ( about 2 mg per pound).
GET HIM TO THE VET IMMEDIATELY. Zyrtec may be harmful or fatal to dogs if it is swallowed.
No, this would be a very high dose. Call your veterinarian and ask how much Benadryl to give your dog.
