I rescue Bull Breeds and I've been using Doggy Daily Immunity Boost on my Red-nosed Pitty (9 1/2yrs) and my American Bully(almost 9yrs) for several years now. Both breeds can be prone to all sorts of skin and food allergies and my boy had major issues when I rescued him.
I went through many different products (spent $2k in the first year of having my boy and I'm on disability, my dogs are my life and I am their 2nd chance.I take this very seriously) trying to find something that helped balance out the allergies and Doggy Daily has been a huge help at a reasonable cost, very reasonable when compared to other similar non NZ made products.
Can't recommend highly enough!
