How much Benadryl should I give my dog?
Even though we just answered this question previously, we can’t stress enough on the fact that it needs to be administered at the appropriate doses and following the instructions from your vet to avoid unnecessary medical complications.
As we discussed, the standard dosage for oral Benadryl is 1 mg per pound of body weight, given 2-3 times a day.
According to Dogtime.com: One tablet on average can have 25 mg, so a 25-pound dog should be given one tablet.
Check the dosage on the package, and don’t assume that every product will be the same.
It is recommended to use the tablet form only since the liquid form may contain alcohol and it is toxic for dogs.
For smaller breeds, you can use the children’s formula since it is alcohol-free and it can become easier for you to measure and get the appropriate dose.
There is also a topical form that can help when your dog has an itch. Fir any creams and gels it is necessary to follow your vet’s instructions.
Lastly, Benadryl can be given to your dog around every 8-12 hours, meaning 2 to 3 times a day but if you use it more frequently your dog can become tolerant of the drug and it will lose its effect.
Recommendation from Pet MD: Always double-check the dosage before giving an over the counter medication.
In addition, many formulations are combined with other medications such as Tylenol so make sure Benadryl tablets contain only diphenhydramine.
When to contact your Vet
Oral Benadryl is considered to have a mild to moderately effective antihistamine property.
