Hi I have a bull mastiff called blue ,who is almost 8 but suffers with bad arthritis due to back problems I am giving him cbd oil bought from america he has been on 3 drops 3 times per day for two weeks now. He hasn’t got any worse not seen a lot of improvement as yet but haven’t got much left in bottle. Thinking of continuing him on simple cbd gold which I have read could help and b much cheaper. Need some help how much to give him and is it the right one for him. Need some help here please.
