WORKS FAST AND EFFICIENTLY
MIRACLE WORKER!! Seriously this stuff saved my dog. He was itching so bad and licking, he began to have small open wounds from all the licking and scratching. His whole back scaly and red and his poor tail was totally encrusted and nasty. I will say I didn’t take him to the vet, the economy is hard enough as it is and I just couldn’t afford a vet bill plus any prescriptions. I did research as best as I could and came to the conclusion he caught mange and it was totally taking over his lower back and hind legs. I did as much research as I could and came upon this product. On a whim I ordered it and am so grateful it lived up to all its claims!! I followed the directions and applied it one day on one day off. And would bathe my dog at the end of the week. I did this faithfully for two and a half weeks. The first photo was taken on Aug 4th and the update is Aug 17th. I was also worried the damage to his skin would affect the hair regrowth but as you can see his hair is growing back quickly and healthy. He has not itched or whined like he normally was due to all the discomfort he had. I did have a cone on him 24/7 through out the process and am still keeping it on him for another two weeks to be totally sure he is fully recovered. For reference if necessary my dog is a yorkeepoodle weighing 17lbs, and I applied it for two weeks and am barely at half the bottle. Should I ever need it again, it should be enough for another round of treatment. CAUTION: IT STINKS!! BADD, it smells like gasoline or burnt tire. A true industrial chemical smell but I didn’t care and made sure to apply outside on my deck before bringing him in. I didn’t have any issues once I allowed it to dry which took about 10-15 minutes with it rubbing off on clothes or couch etc. I did regardless keep him more isolated during this time to ensure it wouldn’t rub off anywhere. Only thing I wish it was easier to dispense. I bought a pack of gloves and cotton pads during his Treatment for easier application and found using a small glass bowl I could use after shaking the bottle and pouring some in the glass to dampen the cotton pads and apply was the easiest way for me to get it done. Other wise pouring straight out of the bottle it gets messy and drips and trust me with how bad it smells you don’t want it everywhere

Works amazingly, smells equally bad.
My AKC Doxie has the most problematic skin of any dog I have ever had over 50 years. She developed patches where it appeared to be psoriasis. Turns out it was mites. I had tried everything over the last 3 years to aleviate her itch. The spots were scaly and the hair was missing. I tried shots prior before the psoriasis like mange appeared. Bought this out of desperation. Applied outside head to toe on my pouch. She immediately had relief. Also her skin was moisturized from the allow. She slept alot that first dose. I Applied over 4 days until I was down to just spot treatment and hair was coming back. I never once rinsed it off per the instructions. It appears to have knocked out the mites. Now for the bad. It smells, not super strong but the sulpher is pronounced. Think rotten eggs but a bit more intolerable. The worst part is that the bedding and blankets she laid on are ruined. After 2 cycles with oxyclean and booster, they smell like dead mice. The image I uploaded is after treatment.

Words can't describe how grateful I am
The first time I ever took my dog, to a vet 13 years ago, she said, "Be very careful, he has sensitive skin." I didn't know what she meant, I wish I asked, because since then it's been an uphill battle with his poor skin. He is always itchy, allergic to fleas, gets yeast infections... anything that can go wrong does and he's ALWAYS itchy. We've tried sulfur shampoos, oatmeal, aloe, creams, changing his diet, but nothing provided more than temporary relief. This spring, he started losing fur along his spine and I thought "FLEAS!" Fleas will make my dog go -bald- in a matter of weeks so I freaked out and started looking everywhere for them. No fleas. Not one. Exacerbated, I started my search for the 13th year for something that would help my poor itchy dog. Originally thinking Happy Jack was a shampoo, I sort of rolled my eyes and put it in my cart with some https://www.amazon.com/gp/product/B071WCV19B of these immuno vitamins. Bacterial and fungal infections, as well as mange, can all be helped with a stronger immune system. When I got to the bottle of Happy Jack, though, I was disappointed. It seemed expensive for so little shampoo. And then when I read the instructions, that this was to be rubbed into his skin and left to dry, I was extremely dubious. He's a pekingese with medium length fur... he'd be wet all day. Still, I followed the instructions, put on my kitchen gloves, and started smearing him in this very foul smelling oil. I expected him to freak out, since he hates the smelly sulfur rinses, but he immediately relaxed. He let me massage his whole body in oil, loved it! Was upset when I stopped! And then... he slept for hours and hours and hours. Peaceful and soothed. I repeated until the bottle was empty, about 5-6 days. The smell is overwhelming for me. My whole house seemed to smell of pine tar and it covered my tongue and throat. Who cares?! My dog felt amazing during treatments and itching was reduced 90%. It's now been 2 weeks since treatment... Dog is doing great. I see 75% reduction in itching, the bald spots are robustly growing new hair, the skin is white and clear. Even the black spots on his belly lightened by several shades. I plan to buy another bottle in a couple weeks for more spot-therapy. I want to treat his most targeted areas maybe once a week to keep him as comfortable as possible. I also want to treat his tummy to see if we can't get it a nice healthy color. It's been a long road but my dog is actually sleeping through the night... which NEVER happens. He'll sleep in! He doesn't have to be babysat because he rolls around all day. He doesn't itch himself until he cries. And that is worth ANYTHING. Thank you Happy Jack for being a cure all for ALL the itchiness that plagues my poor dog.

It works fast.
I can't believe how good and fast this medicine works. It heals fast. The itching stopped almost immediately after I applied it. It's the third day and the open wound she had is almost healed completely. She hasn't scratched at all since I applied the med. Yes the med has a strong scent, but I'm willing to deal with it. As long as my baby heals, I don't care one bit about the scent. She gets excited when she sees me put on my gloves and grab the bottle of Happy Jack. She's very happy and I'm very happy with the results.

Good product, bad packaging
Seeing an improvement with my dogs skin but the bottle had to be cut open to use. Horrible packaging and the child safe lid would not open for me.

Asthma, burning eyes, too much!
I wanted this to work soooo bad! But it did nothing after a week of applications. It smelled soooooo strong that it gave a member of the family asthma issues. It is not possible to keep this off of your rugs, furniture, even hands. It takes like 12 hrs to dry, and even then has an oily residue. Someone touched our “dry” dog and then touched their eye and their eye started burning! If you have an outdoor dog, this may work..but indoor dogs it’s too strong of a smell, too hard not to get on humans or household items. I paid a fortune for this not to work. Very disappointed! Oh yeah, our dog hated it too! He would run away and fight us to put it on, sulked when it was on.. it’s all just too much!

Happy Jack works!
This product did exactly as advertised. My Cavalier King Charles Spaniel came down with mange and I shaved him down and treated him as directed. It took about 2 weeks. I'm a dog groomer and this is the first time I've ever seen mange until a client's dog I haven't for 2 months came in with a mild case. I recommended this product and he ordered it. We have a large deer population in our metro area and I've seen deer with rough looking hides. Squirrels as well. The parasites can survive for 48 hours without a host and can get on our pets if they are in our yard. I was afraid I was going to loose our dog thinking it was a food allergy, but he is doing so much better now. Thanks Happy Jack for a great product.

Very helpful although some people may not like the smell lol
It really helps my Bichon boy’s skin. I asked my mom she said the medicine in it is really traditional way of treating mange problem, even for human. It irk very well. Rub and Leave it on my boys skin for 15 mins and wash it away. It smells natural although strong. And you need to wash thoroughly. I didn’t shave his hair so his hair may last some yellow color of sulfur, and the smell of the sulfur. But I feel it smells very clean and medicated lol.

Best Bang for your buck
This stuff smells nasty, however after 5 light treatments every other day and one application 3 days in between the last one, my Chocolate labs 5 inch by 4 inch circle of mange completely disappeared and his nice dark chocolate fur is finally growing back!!! Best bang for your buck PERIOD! Wear one rubber glove and massage it into the spot.
