With all the info on the internet, I’m getting lost in all the hype, reviews, etc. about vitamins and probiotics. Without going into the novel that is my 3 yr old dog and after finally figuring out protein allergies/tummy issues, we’ve had almost a year since I adopted her that we haven’t had any digestive problems. Due to her very restricted vet diet that I can only add veggies to for variety, I want to make sure she is getting as well-rounded a diet considering its limitations. Her prescription dog food is supposed to meet nutritional standards and has a limited amount of probiotics. Is there a single supplement that would be beneficial to add that would have a bio-available multi vit/min AND probiotics at a higher level? Or is this just throwing money to the wind as in: It might not help, but can’t hurt category? Again, not currently dealing with any digestive issues, just want to make sure I’m doing the best I can by my girl. I had planned to do a real food diet, but that is now out of the cards. Thanks!!
