Hi , just got this message, sorry I'm late. You can add a capful in the food and mix it real good, mine don't care for it either in the water but I fill there bowls about 3 times a day, so it's weak. The Regenex I use for their joints also has it in. I don't use alot. I have an article from a vet to use the white vinegar with with water as a rinse and she really likes to use that for the coat and skin. I like that too. Mix 2 gal. water with 1 cup of Distilled white vinegar, pour over the dog and let it on. Dry pooch and that's it. Both uses help deter fleas, tear stains, balancing ph, yeast. I notice it's listed on lots of labels.
When I mix up a batch of homemade food, once a week, I make 8 quarts at a time, I add 1/3 to 1/2 cup ACV . hope this helps,,, How is Sarah?
