The Appropriate Benadryl Dosage for Dogs

How to Administer Benadryl to Dogs
Most dogs will eat just about anything you put in front of them. However, there are those picky dogs that you have to trick. I usually stick a tablet inside a piece of bread and that works. Some dogs are a little smarter than mine and need different options.
Pet stores sell various types of treats that come with a hole in which to place the tablet. Dogs are usually so happy to get treats they’ll just gobble it up in seconds without even noticing the pill.
If you are using Benadryl capsules, break one open and sprinkle it on the dog’s food, mix it with a teaspoon of peanut butter, or sprinkle on a piece of toast.
REMINDER: Refer to the Benadryl dosage chart before using an entire gel cap! A small to medium dog doesn’t need as much of the medication. You might have to buy a tablet that you can cut into appropriate sizes.
Side Effects of Benadryl for Dogs
It’s always worth pointing out potential side effects. The most common side effects include dry mouth, fatigue, rapid breathing, and urinary retention. If you’re sticking with the Benadryl dosage chart, however, most healthy dogs will not show any serious side effects. You may not even notice the ones noted above.

Disease versus Benadryl for Dogs
Never assume that that Benadryl dosage chart is right for all dogs. In fact, your veterinarian may have very good reasons for not recommending the medicine at all.
If your dog hasn’t been to see the veterinarian for a while, he/she may suggest a visit. The reason for this is so that the dog can be examined for underlying conditions. There’s a chance that your dog needs more than just Benadryl, or that the problem you thought you were treating wasn’t actually the whole picture.
