I got this product in the hope that it would help my bulldog regrow his fur in a few spots. When he was 6 his right knee/leg was shaved for TPLO surgery and 5 months later his belly was shaved for an ultrasound and he was diagnosed with IBD and put on a steroid to control the inflammation in his intestines...this was nearly two years ago. Once he started on the steroid the fur stopped growing in. He even started to lose more of it his shaved areas. I was able to get it to come in a bit with melatonin and coconut oil, but that doesn't seem to be doing much anymore. I have only been using this product on my dog for about 5 days and am already seeing some new fur growth. Fingers and paws crossed it keeps growing.
