Hi jacustomer-w1s5sb1p~

As you may or may not know, betalains are named after the Latin name for the common beet (beta vulgaris), which is where the first betalains came from. These betalains are also found in many cacti as a result of the betalain pigments.

Nopal cacti is a family of cactus which are mostly harmless, however the Prickly Pear version is very toxic to dogs, even in small amounts. There's a list of toxic plants, veggies and fruits here: http://www.acreaturecomfort.com/toxic.htm

If the supplement you're taking is NOT made of the toxic versions of Nopal cacti, then you could try using it in your dog to see if it helps like it did with your bursitis. Of course, the best thing to do is to consult with your vet first, just to be sure they think that your dog has a strong enough system to process the supplements.

I hope this helps.

Hi again~

Sorry it took me a bit to get back to you...the dogs made it very clear that they wanted a walk right now and there really wasn't any arguing with them (they out number me).

The same type of betalains that are in your cactus juice are also found in beets...which are very, very dog friendly. I did a little research and found a supplement that might be worth looking into here: http://www.amazon.com/Olewo-Dehydrated-Beets-Supplement-1-Pound/dp/B0083QBWLE (this one is a dog food supplement...I woudln't use it in place of your dog's regular diet, but rather as an addition to it).
