A black dog with a blue collar sits beside a packet of dog food and a bowl.

muddypawsrescuenyc When he first arrived, he was in a bit of rough shape. He was found as a stray, so no one knows exactly what his past was like. All we know is that his future is as bright as his smile! After a few bags of @undertheweatherpet Chicken and Rice (which he gobbled up too fast for us to catch a good photo, yum!), and continuing medication for his stiff joints, Tavo is perking up and has blossomed into the most perfect gentleman.

Amazing results fast! Our Pitty was having a flare up and I decided to try this. He is now holding his leg up sturdy to pee again and has more energy it seems. I can definitely tell this product works! Definitely worth the money! Thank you!

olivemygolden The greatest product ever invented (especially if you have a golden that will eat anything ). I always keep some on hand & they always get used up @undertheweatherpet

Finally found a powder for my picky eaters! My cats don't like seafood flavored anything. It was a great relief to find this product. They happily eat it mixed with their wet food.

Instagram User Thank you @undertheweatherpet for all the wonderful products! Being a foster/rescue mom 🐾 and having rescued an anxious and picky husky 🐶, I can really appreciate your products!


We have freeze dried bland diet for dogs (a quick food replacement when I’m in a pinch - and SUPER healthy for your dog), hemp calming treats for prone to stress pups, and (I know we don’t want to talk about it, but so needed!) anti-diarrhea to help firm up those loose poops 💩!


Skye definitely is an Under the Weather Pup!

No longer ‘Under the Weather!’ Our 15 year cocker, Peanut, has multiple issues and most foods make her so sick and unhappy. But now she is dancing for dinner again. Also, she gets happy when she sees the kettle boiling as she knows what’s coming! Thank you for making such a good product for fur babies.

    Customer Feedback:

    Our Bengal kitty is 16 now and he had a little sag in his booty that made him look his age. We use this product to give him some extra calories so he would have a little bit more meat on his bones and he looks great! I think it gives him a bit more energy and better quality of life.

    Customer Feedback:

    I was hopeful that your product would be what we needed for our little Mischief. \nMischief's is only 3, and has always been a slight cat. Her shots and well-kitty checks are on time. \nThe vet tells me she is "healthy" she's "Just a small cat" (not even 6 lbs)\nI was looking for something that would help her gain some weight and make her coat look thicker and shinier. \nShe ate her 1st dose well, but since then, she won't TOUCH it! \nAlas, we will have to try again. ,\nThank you for being there for us. If I am in need of any other healthy pet products, I'll come to you!\nThank you for having a website for those ofr us with special-needs pets.\n\nTonya & Mischief
