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!

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.

My cat doesn’t like it

"My cat loved it on first bite but then just said no. So I have applied it to his paw on a couple of days when he just wasn’t eating. My cat is very sick so his vet said to be careful with these supplements as they can cause diarrhea. So far so good with that. Since he isn’t eating it daily, I can’t see a difference resulting from this product but I will continue. I have only used the powder once but he wouldn’t eat what I mixed it in( he might not have anyway) but no idea if it’s beneficial."

— Jeniece M. (3/5)

Neither of my cats would eat it.

"Probably not the fault of the product, but the pickiness of my cats. Tried several times to get my skinny girl to at least try it and it was a no go."

— Lea V. (1/5)

Great products

"I have used these products multiple times and would suggest for your cats if you need them."

— Cheryl M. (5/5)

My picky cat doesn't want to eat

"I can't give a fair review of the benefits of this because my cat is refusing to eat any food that I mix it into. I was hoping it was going to have a more palatable taste so my cat would eat it. He's 17 and extremely picky. I'm trying to force him to take the gel, but the powder is impossible to get him to eat."

— Nancy J. (3/5)

Our skinny Minnie little old lady loves both

"We started getting the syringe supplement when our 12yr old developed thyroid issues. No matter what she ate (and she's really picky so it was an adventure trying to get calories into her) she couldn't keep weight on. I tried Under the Weather out of desperation and holy buckets was it a good call. She absolutely loves it and it's been a regular part of her intake for nearly two years. The powder we just recently tried as an addition for her, and also for our long haired boy who despite our best efforts just throws up a lot. Adding this powder to wet food for them both has increased intake (yay, less money wasted on unfinished food!!) and helped both put on a little extra weight. I know every cat has different preferences, but these are a game changing addition for our feline home."

— Kathryn K. (5/5)

"My cat hates it."

— Denise (1/5)

"My cat won't go near food that I put this in. Not even food that he usually likes."

— Richard (1/5)

Unfortunately I can’t review this

"Unfortunately I can’t review this product because my cat has declined to the point that she’s barely eating and very inconsistent with what she wants"
