Questions & Answers

4 Customer Questions

Can the syringe be reused with your own food or something else like vitamins? Or is it a one time use only? I have a sick dog that needs to be force-fed.
Answer by ChewySep 21, 2020
The tube can be reused. Simply pull the plunger out from the tube, clean it well and then it can be used again.

How long will this stay good once opened? Does it need refrigeration?
Answer by ChewyDec 19, 2022
This product is shelf-stable and there will be an expiration date stamped on each tube. It does not require refrigeration after opening, but it is recommended to place the cap back on firmly and use it until it expires.

Is the under the weather ready cal for puppies too
Answer by ChewyNov 03, 2022
This supplement is formulated for adult and senior dogs.

Is this a good supplement for a dog who has Valley Fever and losing weight?
Answer by ChewyJun 01, 2021
We recommend speaking to your vet to see if this would be suitable for their current treatment plan.

Top 1000 Contibutor

This stuff is great!

I have a 17-year-old chihuahua. Her perfect weight is 6.5 pounds and for years her normal weight was 7 pounds. The past couple of years she has been losing weight. The vet says it is a normal ageing process. She got down to 3 pounds and I have been trying everything for her to gain some weight or at least not lose any more. I was even cooking her chicken and rice with gravy or hamburger with gravy, but nothing worked. I have been adding this Under the weather gel to her food for a week now and she is right at 4 pounds. I couldn't be happier.

Works Wonders

2 of my babies had gastro enteritis and were very sick. This helped them immensely, along with other things...but without this I may have lost my 10 yr old mini schnauzer. Before I started using this supplement, she had goten very weak and was wobbly in her back end, but in 2 days of her taking this she was starting to feel better. She wanted to go outside to potty and wanted to eat (chicken broth and rice). I also have to thank Chewy for seeing these products in my order because it was here in less than 48 hours of ordering (I couldn't find locally so I had to order). I have never received my autoship that quick, vut someone was heads up with my order and I am so grateful for that and Chewy.

Too thick and firm

I had high hopes, but can't even use as it's so firm you need something to cut it from the tube, then it doesn't mix unless you melt it. Since I use for tiny pups, I always put supplements in a syringe, which there is no way to do with this product, I ended up warming water and putting gel in water then syringing into pups

Pup Doesn't Like Taste

Our elderly bulldog dog is sick, on meds, and refusing to eat dog food. He's usually on a special low protein diet but I am pushing just about any and everything he will eat at this point. I got this as a nutritional supplement and he hates it. He also hates the Tomlyn malt flavor. Since he loves bread, I am hiding it inside hot dog bun pieces and he's tolerating it so far. I didn't realize this was malt flavor also but we're making it work. He's usually a foodie hound and will eat any and everything. I think the meds are making him nauseous so it's hard to tell if he would like the flavor normally. Right now he's extremely picky.

Vital Calories for Cancer Patient

For any pet lacking appetite, but still needing to keep weight on or have Rxs taken with food, this product is a godsend! Our Husky, who was just diagnosed with an inoperable cancer, had stopped eating just about everything until we tried this. She was sustained on this for days until the medications kicked in to help her appetite. I also can't praise enough the large, measured syringe it comes in. This syringe is super easy to use, easy to dispense small amounts (whether in the mouth or on my hand for her to lick), and easy to keep track of how much has been eaten. Plus, the very sturdy syringe is reusable: it comes apart for easy cleaning and is refillable. I'm going to put baby food in it, for instance, so I can easily keep track of how much I'm feeding. Don't be intimidated by it's appearance - this is perfect for sick dogs! And thanks to Chewy for shipping this and our subsequent orders so quickly, that we could take care of our patient!!!

Saved Joey's life!

Recovering from surgery, my little dog stopped eating and was losing weight rapidly. Chewy delivered this the next day and it was so easy to push in his mouth several times a day til he got his strength back. Don't let the sugar confuse you, it acts like an electrolyte for dogs. Joey loves it.

No go for my dog

My dog is in his late years making him a picky eater and he is basically just burning calories living. So I wanted this in hopes to put some more weight and nutrients into his diet. Sadly he did not like the taste at all. I even tried coring hot dogs and loading it in then cutting them into pieces. I wish he had liked it more. But I say it is still def worth the try. Just because my pupperoni didn't like it doesn't mean yours will feel the same.
