My old husky Lumi has cancer, losing her hair & struggles with movement. I came across Oil Science CBD for pets and I have not looked back. She has virtually had all her hair grow back and I can see an improvement in her. I opted for the subscription as 1. I did not have to order every month, this would be automatically updated for me which saves time and effort on busy days, and 2. It is an excellent price when I moved to subscription as I was able to save over R100 a month.
