Hopefully healthy
I didn’t give 5 stars because my dog has only been taking it 6 days . I do think I’m seeing an improvement in his energy . He really likes the taste of it ! I’m hoping it does all that is claimed in advertisements . My little dog will be 11 yrs old in March and anything that helps keep him healthy will be wonderful ! I’m very hopeful this a real health boost .

Disappointing
Tried several methods to get my cat to consume the supplement hoping it would help to alleviate her allergy symptoms but she refused it every time.
