Hi everyone - I'm going to try to keep this post as concise as possible while still giving you the big picture overview of the issues. I'm hoping for some advise and I know that this forum is always the best place to get good information. I also don't have 100% all of the facts - my mom does and she has copious notes - I am reporting what I know and can fill in added details from her in later posts if necessary.
I'm writing about my parents' lab Shiloh. He is a large lab: 100lbs normally when not completely fit, and low/mid 90s when in good condition. Due to his inability to have lots of exercise (explained below) he's mostly been around 100 lbs the past few years.
We adopted him from his former foster home in the summer of 2008 and they said they thought he was 9 yrs old. We believe now that he was a few years younger than that at the time. He smelled funny and his eyes were kind of glassy when we got him; we suspect he had been fed a low-quality kibble. My parents have fed him raw ever since and the smell and glassy eye issues went away after a month or so on good food. Other than occasional bouts of diarrhea (we believe he has a pretty sensitive digestive system), he's been good with this diet ever since. He didn't seem to do well with higher fat foods like pork riblets; his main foods have been small game hens and ground turkey I believe.
In the summer of 2009 he ruptured a disk in his back and was paralyzed from the waist down. He didn't have a great chance at recovery but he had an excellent, excellent neurologist who was able to clear out the debris. After 5+ months of recovery, he regained his ability to walk, though the rear right leg has always been the hardest for him to control. Some days have been better than others, seemingly based on the amount of inflammation around the spinal cord where the injury happened. He's been on Deramaxx for the inflammation, and occasionally Tramadol for pain.
Over this past summer he had a gradual, slow decline of his walking ability, particularly in the rear right. This had been expected to probably happen at some point. At his worst over the summer (after trying to chase a squirrel or something), he got down to maybe 60% of his "best" post-injury abilities. In early Oct, my parents took him to see his neurologist to see if there was anything else we could do. That's when all the trouble started, roughly 2 months ago.
The decision was made to try Prednisone rather than the non-steroidal anti-inflamatory Deramaxx, hoping it could clear out some of the inflamation around the spinal cord and give him some greater leg control. At that time they also discovered that he had some mast cell tumors which weren't huge problems yet but which will likely kill him eventually. The added hope was that the Prednisone would shrink the mast cells and make them less of an issue for a while, which it did. The mast cells shrunk a lot over the first few weeks so the vets were happy with the results from that.
Since that time, the primary problem is that we have had essentially a non-stop run of digestive issues, starting right when he returned home from the neurologist appointment. I should add that this is an overnight trip as the neurologist is 4 hours away. Locally my parents have been seeing two different general practice vets - two, because invariably Shiloh's weird health issues have been flaring up as soon as one was on their day off, often when both are on their days off.
I don't remember the symptoms exactly when they returned to town, though my mom has a pretty complete log. I believe he had diarrhea and maybe seemed nauseous. Throughout all of this though, he has hardly ever thrown up. Maybe only once or twice at most in the past 2 months. My parents had fed him some slightly different foods while they were out of town so at first they thought his problem was from that. He wasn't on the Prednisone yet as he was in his detox from Deramaxx at the time. I don't know if he'd started his prilosec (to protect his stomach from Prednisone) yet or not, though he may have since I believe he was supposed to be on the Prilosec for a few days before starting the Prednisone. So probably (my mom can clarify) he went off Deramaxx and on to Prilosec, with the intension of starting Prednisone a few days later.
Nevertheless, the local vet (possibily incorrectly) diagnosed him with Pancreatitis and had my parents switch to feeding him the horrible Royal Canin low-fat canned food, which was a disaster. I would add that while he has been eating some food since the beginning of his troubles in early Oct, I don't believe he has had a decent balanced meal since that trip to the neurologist.
Shiloh didn't like the Royal Canin and didn't want to eat it. It also gave him gas. After a few weeks of that, the vet finally recommended trying him on boiled chicken and cooked sweet potato - in a ratio of 3 parts potato to 1 part chicken. This gave him horrible gas and he quickly grew tired of it. My mom finally switched it 1 part of each and that helped, but he quickly grew tired of that ratio too and refused to eat any more of it. He only wanted the chicken.
Over the past month (approximately) they have gotten him onto more cooked ground turkey, cooked ground beef, and cooked ground buffalo, but almost strictly the meats with very little of anything else as he doesn't want the sweet potato any more.
Every time they try to add something, even very slowly, he gets diarrhea. They have been feeding him very small meals multiple times a day, which does help, but he quickly tires of a food and refuses to eat it. He is hungry though. He wants to eat but will look away from something (like ground turkey) that he has eaten for a few days, and only wants something new. Our speculation is that he is having nausea issues and becomes superstitious about the food he has been eating, but we are running out of novel protein sources.
We have tried THK Verve and Zeal, and the base mixes. I believe they all upset his digestive system. Slippery elm seems to help some, and he really, really likes the dog Sweet Spot sweet potato "ice cream". He has always liked them, but now even more so because he is hungry (and unable to eat much of his other meals). We suspect they may help soothe his stomach but that's just a guess.
He has lost a lot of weight - down to mid-80s now, though has somehow gained a pound or two since his lowest point. His musculature is weak from the lack of solid nutition so we really haven't seen any benefit, mobility-wise, from the Prednisone. He is far worse now than he was before we started down this path in Oct, though there are some days when he has eaten some decent calories and is then strong enough to walk more like "normal". The rest of the time he is just weak and tired.
Despite all this, he still seems to feel mostly like himself and in his face you can see he's still himself and not completely miserable. He wants to eat, he just can't bring himself to do it a lot of the time. We are reducing the Prednisone - I believe it went down again starting last night. My personal hypothesis is that the Prednisone, despite the Prilosec (and the Cerenia which he has been off and on through out this as well), is causing his apparent nausea. My hope is that if we get him off it and the Prilosec, and back on the Deramaxx, he'll be able to eat and return to something approaching "normal". At that point the mast cells will probably come back and kill him but at least he'll have a few good months before then. I believe my parents feel the same way, but it's their call not mine.
As of today, the vets are recommending euthanasia but it seems like the immediate problems have been caused by all their treatments so I'm not inclined to give them a lot of credibility at the moment. They also recommended Royal Canin hydrolyzed soy protein canned food yesterday, so it's hard for me to believe they know what they're doing.
Of course the other possibility is that his inability to eat regularly is not from the Prednisone at all but from the Mast Cells. I think there's no way to know until he's back off the Prednisone and the stomach has a chance to heal a bit and we can try him back on his original raw food (which he can't have while he's on the Prilosec). On the other hand, I don't believe we've seen any visual evidence of mast cell regrowth (he had/has one external and two internal, liver and speen, I think). So the Prednisone seems to be keeping them down at the moment.
I think I've covered the basics in this very long post. We know he's not going to recover and feel great and live another 3 years, and that sooner or later there will probably come a point where we have to euthanize him. We also are well aware of the good advise on this board that it is better to not wait too long for that day. However, while it might be wishful thinking, I don't believe any of us feel like this is that time yet. If we could just get some quality nutition in him for a few days, we believe that he'll have a few more good months in him.
As always, any advise and good thoughts are greatly appreciated.
