My 7 lb Yorkie has 13 Grass Allergies per her Vet Dermatologist - I asked about trying this OTC Pill for my Yorkie to see if it works and wanted to get her off of CYTOPOINT Allergy Vet Shots at $50 per MONTH shot! She has been only on the Pet-armor at 1/4 Tablet PER DAY and works FANTASTIC! She has NOT use any Rx medicine for 2 months and no longer biting her paws or scratching! TRY IT but ask YOUR VET for the amount to give if you have a DOG under 14 lbs!

Don't waste your money

This is benadryl, and it's the generic version. They sell these same pills (25mg) at the Dollar store for $1 for 36 tabs, they also sell generic Zyrtec for $1 also,

This is benadryl, and it's the generic version. They sell these same pills (25mg) at the Dollar store for $1 for 36 tabs, they also sell generic Zyrtec for $1 also, they're only 10mg and only come with 14 pills but they're very small and seem a lot easier to give if your dog is like mine and is to cleaver for the pill pockets or trying to sneak them to her. We have to actually open her mouth and force her to take them which males me feel horrible already, but having the smaller pills that aren't covered in that pink dye is way easier.

Benadryl generic - Diphenhydramine HCI

Our dog, whom we've only had about a month revealed an 'itching' problem. He's a border collie mix. He has a very nice coat and the typical bushy tail and we noticed

Our dog, whom we've only had about a month revealed an 'itching' problem. He's a border collie mix. He has a very nice coat and the typical bushy tail and we noticed he would itch quite a bit. We checked for fleas on several occassions at bathtime and he didn't have any. Turned out he has an itchy coat because he loves the outdoors and we thought the itching was problematic for him so we decided to get this product and it works great. Itching can be caused from sensitive skin (which we found out was his problem) or a variety of skin reactions caused by other things that your vet can diagnose. He's been so calm and we're glad that the PetArmor Diphenhydramine HCI was available at Chewy for such as reasonable price and have been very happy with it!

Worth buying

My Shih-poo had horrible allergies and I had no money for a big vet bill. I decided to try this first and within a few days, his allergies decreased significantly!

Works great!

This definitely seems to be working great. Less itchiness and watery eyes but it does also help to calm them down a bit. It doesn't stop her from wanting to play

It's Benadryl for your dog

My senior dog has cancer and was coughing and breathing hard at night. He was not sleeping well, and neither was I. He has always had very sensitive skin and allergies

My senior dog has cancer and was coughing and breathing hard at night. He was not sleeping well, and neither was I. He has always had very sensitive skin and allergies. So, read that Benadryl could help with these issues. It has been a tremendous help for him, given just before bed with a light meal. Improvement would be a "dye Free" version. Dyes can be an allergen, so I scrap off as much of the pink shell as I can before giving it to him.
