This helped my little dog, Mimi, see again. I bought it for my dog Tootsie, but (and I don't know if the info. insert tells you this) you cannot use these drops while giving a dog steroids (i.e. Prednisone) because it will render the drops useless. So I used it on Mimi. I didn't even realize Mimi couldn't see well anymore. She just looked older because of her big cataracts. Well, people don't point her out and say "she's an old dog" anymore because her cataract is almost gone. But the amazing thing is, she's running and dancing, going up and down stairs, jumping on the furniture, etc. again!!!! I can finally try these on Tootsie as I've taken her off Prednisone. I did get some from another distributor (listed on the Ader website). And Tootsie actually stopped while walking once, because she saw a shadow and thought she'd run into it!! I was so happy I cried. Then, this jerk of a distributor kept telling me he'd send me more drops (after I sent him the $$), but never did. So her eyes went back to the starting point. I'm anxious to try them again. Anyone who says that dogs are fine with being blind and learn to cope is not in touch with dogs. Tootsie has been fearful, angry and frustrated since going blind.I can't say enough great things about this product! It has improved my dogs' KCS. I've tried many things for him; nothing really helped like this has. I have one tube left, I will be buying more. Update: As great as this product works, it still never healed my dog's eyes completely. Very expensive for constant use, and no long term benefit. I'll leave the stars, but probably won't continue use. It did cause some relief, but it's too bad the individual, or drug company is so greedy and severly over charge you to help your "fur baby".This product is expensive, but the results on my diabetic dog with cataracts have made a huge improvement in his vision and well being. He’s 15 so he no longer has sharp vision, but prior to taking these drops he became withdrawn and scared of everything because he couldn’t see. Within 5 days or so I could tell a difference. After several months, he’s happy again and is no longer skittish and afraid. I know $100 / month is a lot, but If you can possibly afford these, get them.Loved the product and the service! I would have ordered more, however it appears it is no longer available online w/o a prescription! My vet suggested the regular Pet Vision as she feels it will work just as well ...I've been using this product on my two senior dogs with cataracts & it seems to improve their vision & shrink them all at the same time!! I hope to see even more improvement very soon. Delivery is fast & package is well packed!! I'm on my second shipment now :)!Seems to be helping my 10yr old with her Cataracts.This stuff works!I have been using this on my dog's eyes for about 4 years when she started to get cataracts. This product has NOT removed the cataracts, but her cataracts has not progressed. I would like to try other products, but I worry that they might be less effective.
