What Pet Owners Are Saying
Quality, Safe, & Effective. Kitty Love It!
My finicky little 8-year-old princess snubs her nose at EVERYTHING! But NOT Dr. Bill’s Feline Immune Support! I add a drop or two of bottled water to the powder and blend with her food to make a “gravy”. She loves it! Kitten like behavior- playful, active, happy, and has a tremendously silky coat. Her once weepy eye is clear and bright. Highly recommend all of Dr. Bill’s high quality products.
Helping My Dog Who Has Cancer
My dog has cancer and was given about two months to live. I started giving her Dr. Bill’s Immune Support thinking it couldn’t hurt. It’s been three months since her diagnosis and she looks great and is going strong.
Great to Keep Our Dog Healthy!
We have an older Australian Shepherd and she loves this! We haven’t used it for very long yet but it seems like it will be a great supplement. She absolutely loves the taste of it, whether we wet or down or give it to her dry.
My cat Enoch was diagnosed with FIV 12 years ago. This stuff has really helped strengthen his immune system. I mix a little bit of this with his soft cat food and he enthusiastically gobbles it up! Highly recommended!
His Hair Has Grown Back
I am on my second order of this product. My dog had hives and was losing his hair in some places. None of the topical remedies were working well so I decided to try this product because I thought he needed to boost his immune system as well. He was a shelter dog and had a skin condition before which was treated with antibiotics. He also had very smelly feet from yeast. I stopped using the topical treatments over a month ago. He is much better now, his hair has grown back and he has even more hair in places where it was thin.
