Devil's claw?

Zeke's on a few supplements for his arthritis and limp including:

Glucosamine, Chondroitin, MSM
Green lipped mussel
Ginger
Linseed Oil
Vitamin tablets in a 'joint tablet' for dogs inc Vit D, E, C, B6 and others.

All the above are in a combi tablet form.

(Not to mention his JWB cereal free kibble and his naturesdiet wet food trays both have some of these vitamins in it + seaweed and omega oils)

BUT he's not on devil's claw which I've heard rave reviews about.

People who use devils claw, is this ok to add do you think, or do you have a better recommendation?

(and can you give them too many natural supplements ) He had cancer last year (lymphoma) aged 6 and is in remission hence the reason we're going down the natural route, he's also having acupuncture at the mo.

Personally I would not give linseed/flaxseed oil as the dog has to convert the ALA into DHA/EPA and thus it is not readily bio available.

Whereas both DHA and EPA are readily available to the dog via FBO.

Devils Claw is fine to give as is Bromelain, Rosehips and Cetyl M.
