I switched from "fresh factors" to "Longevity" because it had more ingredients that would be helpful to my older dog. It is a powder and I sprinkle it on their dinner. I figured they would get sick of it as it seems to have a strong flavor, but they love it. I sprinkle some on the younger dogs food too because they all like it so much. When they have dinner they lick the bowl for several minutes to be sure they get every last bit.

It also seems to work very well for joint pain and overall attitiude.

It is VERY green from some of the ingredients and I've had a little problem with green spots around the house, but they wipe right up.

Overall a fantastic product

Pros: dogs love it, works great

Cons: price and color

when my dog was diagnosed with lyme and her immune system shut down we almost lost her but with a great vet and loads of orthodox meds she came back but with taking many pills each day we sought a way to help her with alternative meds thats when i called Springtime and we went thru what she was taking and how Longevity had it all and more and gradually she was switched over it took about six months to make the switch but is now in the best health ever she is 9 and acts 2! we will always be grateful to the people at Springtime for taking the time to go thru the meds and dosages and helping us to get her onto Longevity

Pros: easy to add to food fantastic ingredients

Cons: not too tasty but my dog liked it very much!

Excellent supplement! We supplement both of our dogs food every morning and evening with Longevity. We have a 10 year old Rottie and a 5 year old Golden Retriever who greatly benefit from the fantastic ingredients of this product. This is very good for older dogs; it brings the "spring" back into their step. We can truly tell a difference in how our oldest dog acts since we've started giving him Longevity.

Pros: Healthy benefits, good ingredients, Dogs love the taste

Cons: Pricey for those on a budget

The dogs I take care of get this everyday and they are very vital, happy dogs. The Springtime supplements really are well researched and work well on the pets.

Pros: It really has good ingredient

Cons: mail order,but fast

Was very helpful to our Aussie when she had problems with her hips.

Pros: Affordable

Cons: none
