Oh Emily!!!!! I'm so sorry to see this; I don't know how I missed your post for so long. *tears* I am guessing your vet(s) showed you some QoL scoring charts that might be helpful as a general guideline; there are a few around, and I did one every week for MP with my rehab vet. It sucks, but it's sometimes good to see it in plain numbers—and it's super helpful to have other family members and friends of C do them, too, especially when there's disagreements re: QoL. Here is one that I found that seems like a good one. https://vet.osu.edu/vmc/sites/default/f ... owWhen.pdf
You've had lots and lots of great input about knowing when type stuff already, so I'll just talk about the stuff I did to try to accommodate/adapt to "new normals" so that you have more good days than bad days.
MP steadily lost mobility until the very end, when she couldn't get up on her own. With lots of help from my rehab and regular vets and ODOers, I realized that loss of mobility doesn't always have to be the end of good things, and there's lots you can still do.
One of the things that became indispensable (for all of us!!) is this harness called the Help-Em-Up (https://helpemup.com/
). It's made so that they can keep it on 24/7 if they have to, and that's pretty much how MP used it towards the end. Before getting the Help-Em-Up, when she started to knuckle one of her rear feet under, we used this elastic rear foot brace type thing that helped to flip her foot upward. (Very much like this one, but hers was shorter/smaller: https://www.handicappedpets.com/no-knuc ... ning-sock/
) If C likes to explore beyond walkable distances, then a cart or a wagon or a stroller might be a worthwhile investment. Walking and going to parks was a super big deal to MP, so after we started to run out of very short-and-easy-but-fun trails, I got her a stroller called the Doggyride—and it really helped to keep our world opened up for us. Literally a life/spirit-saver for both of us! Car rides are great, too, if he likes those! MP also liked to do tricks for me, but most of them were too hard/physically demanding for a gimpy/unstable dog, so we did a lot of variations that were very face-oriented (touch, kisses, look at me, push a ball with nose, etc.) and didn't require moving owie legs.
All in all, I just kept experimenting with new things she liked. I probably annoyed her quite a bit in the trial & error process, but I was desperate to make things not suck! I found out that she suddenly really likes ice cubes, so I got a big thermos filled with ice that I carried everywhere, and I froze lots of things like fruits and other foods. If C likes that bush spot in the yard, and if he suddenly likes cooler temps, that's OK! Anything he shows you that he likes, that means you could let him do more of, or replicate elsewhere (make house cooler; get cooling mat; ice cube snacks; ice packs on bump). I think seeking the cold might be an old dog thing, too—I know several old dogs who would insist on being out in the MN winter cold!
Last summer, my house was *freezing* with AC blasting and fans on full speed.
I think it is really great that he loves food still.
MP ended up on some hardcore abx (Orbax) that seemed to help her feel better for whatever reason—my regular vet thought there were probably things that were festering and inflaming and it was knocking it down.
Re: CBD products—the only capsules that seemed to work for MP was Canna Companion brand. It was a world of difference compared to Canna-Pet that I was using at the beginning, although it could very well be that she was simply not getting enough Canna-Pet. Both companies had very helpful vets and techs who gave me individualized hand-holding re: dosage, etc. For oils (faster acting, less amount to take), I liked the Endoca brand. MP ended up needing a much, much higher dose that what's on the packaging and for general use.
You are doing great, Emily! It is the *worst*! I cried the whole time I was reading and tying here; I hope what I wrote makes some sense because I can't go back and proofread it. Sending you all the good everythings. We are here for you!
