I could use any words of wisdom, advice, etc here.
Please bear with me, here's the background....
About 4-6 weeks ago, our 11 1/2 yr old mutt (58 lbs) Fred started limping on his front right leg. We kept poking and prodding to see what was wrong and he never yelped or acted like it really hurt other than not using it...we assumed he just pulled something running in the field and kept an eye on it. Then about 2 weeks later we came home to evidence that he'd been coughing up blood...what seemed like a lot. So off to the vet we went. They did blood work and found nothing. It looked like his red blood cells weren't being replenished and the vet didn't know why. He is free of parasites and any disease they could test via blood and fecal there. The only thing left for them to do was an x-ray but anything it would show we wouldn't be couldn't afford to treat anyway.
The vet figured his leg was arthritis, given his size and age and the blood had them stumped. He quit coughing it up that day. A few clots came up a day or two later but it was obviously old.
Well, a few days later I had to go cross country for two weeks due to a death in the family. My husband was home to care for him.
I returned to Fred not using his leg at all, and he'd lost a significant amount of weight. My husband said he'd not been eating well or at all. I can see his backbone and ribs and even his head looks like it's lost weight. He only gets up to go to the bathroom and drink. It takes him quite a bit of effort and time to get up. I've managed to get him to eat some tempting canned dog food but he still doesn't eat as much as I think he should. His breathing is always laboured. It's hard because he still wags his tail, his eyes aren't dull, and he will get up if you really really coax him to get up and eat or go outside. But he doesn't stray more than 20 feet from the house, where he used to wander and run around our few acres.
Anyone have any thoughts?
