Here's my suggestion that saved a dog (not mine) from euthinasia two months ago
A product by Genuine Health (may be a canadian company, there is .ca links and .com links so not sure if readily available or has to be shipped), anyhow...It's called "Fast Joint Plus Care" with claims of 5-10 days. Well...5 days my dog went from being completely immobile to getting up to greet me again, within 10 days he was voluntarily going on walks and was smiling again (was hand feeding him as he was in too much pain to go to his bowl)...(he had a knee injury, and was in very bad shape...a long story).
This product mad a huge difference in getting him going so his muscles didn't atrophied any further. I was also using a product called Wobenzyme (still do) for inflammation.
Eventually I couldn't maintain the expence of some suppliments including calcium so I dumped the F.J.P. and calcium and started making ground eggshells, by fluke I happened across a blurb about chicken stock (something I already knew, but...well it was just one more thing to do and I was beat)
I had been rehabilitating him for several months, and he had good days and bad, then Dec. hit and he was baaaad! I thought holy crap, my poor dog at 7 yrs. old and is walking like a 14 yr. old, I was sooo sad, he is too beautiful to have his life cut short.
SO, I grabbed some frozen chicken frames, my slow cooker, some vinigar...Made my first batch on Dec. 29th/2011 (most fat removed prior, and the rest skimmed off - strain bones)...On Jan. 30th/2012, I was preparing to take him on his final walk of the day...he headed into the bedroom (I had made a bed for him next to mine where he slept for 10 months)to "get ready", I went to brush my teeth...then went into my room expecting to kneal down to give him "bellies"...HE WAS ON MY BED!!! I nearly fainted...10 months he couldn't jump up, within 30 days of feeding him chicken stock he was on my bed.
HE didn't go up there again (that I know of) for another month, but was tearing down the road on walks, had a spring in his step again, and now....I can't get the knucklhead off my bed
The woman I met two months ago dog exhibited the exact same issues as mine, her vet suggested euthinasia.....within two weeks of FJP and chicken stock, her dog was walking a half an hour, she called me a couple nights ago...he is bounding and swimming and chasing stick and climbing stairs.
Try it, it can't hurt (NEM - on the website link stands for Natural Eggshell Membrane)...you only need 1 per day, and the chicken stock...1/2 cup to a cup...make a huge batch and freeze, but has to be chicken for the cartiledge...(type 11 collegen)
