The amount of abuse some of these dogs go through and they still loove humans...poor baby. I use what ever comes to me. Since trainer, i get free samples in the mail. I use olive oil too. I used to use the liquid flaxseed oil, she really likes it...but it is so much more expencive then the caplets, and the caplet last longer. So for now i use the caplets and use 1 tablespoon of olive oil.. she likes it. even though they are deaf they can still know what you want from them. Jaz knows no, sit, down, roll over, walk, poo/pee, come, heel, paw, sit pretty, crawl, up <-- on my shoulders, up <-- on bed, sit on couch, stay. There is so much they can do!
