I have a rescue pup 8 MO old and he was not nutritionally sound, dry coat, itchy skinny. I have a Cane Corso 9 year old. I make my own food so it is important that they get a good supplement for minerals, pre and pro biotic etc. I have been feeding them this for a month I give the big girl one scoop in the morning one at dinner and the pup one in morning. The pup now has soft fur, no itching skin. Big dog is shinny and soft fur. I k iw this stuff is a bit strong smelling but when mixed with the home cooked veggies and meat and eggs. I will never buy pet food again but I will buy this supplement product again.
