we use salmon oil only, and not every day. we buy it in bulk and put it in a squirt bottle...makes it easy. the result is a beautiful coat, and other than that, i'm hoping it keeps their hearts strong.
I use Flaxseed oil capsules for Babygirl and Fish Oil capsules for Mr. Wilson and Louie. I've got some Probiotic capsules and Psyllium Husk Capsules for my Frenchton on order. Seems like these kind of nervous dogs always have digestive issues and has always had loose bowel movements. He's on the same grain free food as the Bulldogs. Will post updates to see if there are any good results.
I've used salmon oil as well. Samson had bald spots and it really helped with them, as well as his nice shiny silky coat I think I just did one squirt per meal
I use Fortiflora probiotic. Poppy used to have a weak stomach, she would always pick up a GI bug after daycare or boarding. I knew for a fact the facilities she was at were immaculately clean. Vet recommended a probiotic, since Oct she hasn't been sick or had diarrhea. Woo hoo!!
I use Vetri Probiotics Everday Bite sized Chews and a Chewable Multivitamin/Mineral supplement daily for both my Dogs. Without the probiotics, their poop is horrible.
