High-Protein Training Treat That My Dog Loves
Size: 1.31 Pound (Pack of 1)
I got the MON2SUN Chicken Jerky Dog Treats (Made with Chicken Breast, High Protein & Grain Free, 21 oz) for my pup and have been impressed. The treats are truly made with chicken breast and grain-free, which gave me confidence in the ingredient list. My dog’s eyes lit up when I opened the bag, and the pieces are appropriately sized for training—easy to break into smaller bits for quicker rewards.
Recommendation: If you’re looking for a quality, high-protein, grain-free treat for your dog (small to large breeds), this is a solid choice.

Its basically glycerin in a gel form.
I have only tried another version of this, but the biotene version is water based and not oil like I tried. I put a smudge of this on my finger and suck it off. I assume that's the right way, the tube is a bit small though. But it does last a pretty long time. Basically its glycerin in a form of a gel, and its tastes sweet, does it work? Yeah, more or less. I place it on the roof of my mouth and dip from there, but when done, i still need a drink. But its helpful if your mouth is dry and you keep having to drink a ton of water to get to sleep. So I get a bit of this. I'm hoping to find a way to make it myself though.

Good, super useful - worth the money
Works well. I use it with a mouth guard that helps with grinding my teeth and this product seems to protect my gums.

Biotene WORKS
Dry mouth happens at night because of my cpap. My dentist recommended Biotene and it was a great relief for my dry mouth problem. Highly recommended!
