So the Megstar had her first Librela injection today and now I am watching and hoping. One plus, it wasn’t as expensive as I feared, at £60 (around $85 US). I’d expected around £100, (and have actually just taken on a bit more tutoring to pay for it) so given this is a monthly jab (if it works) that makes quite a substantial difference. 
BTW I think there’s some misconception about monoclonal antibody treatment, which I myself shared until I discovered more about it. The injection is tailored to each species, but not to each individual animal.  So there’s one for dogs, another for cats, another for rabbits and so on. If it had to be tailored to each individual animal then that would obviously be much more expensive. Anyway, here’s hoping...

That’s right. No loading dose. It works in a completely different way from other treatments, as I understand it. 

Thanks for checking in, Sally. Meg has now had two doses of Librela, four weeks apart. After the first dose, I didn't notice much change, but the weather was truly terrible, just endless rain and cold and damp, which aggravates her arthritis in any case. I have read that most dogs don't notice an improvement until  after the second dose, and I am delighted to say that this is clearly the case with Meg. It wasn't immediate, perhaps two or three days after that second dose, but I then quite suddenly saw a marked improvement. We'd gone to the seaside for the weekend, which always sees Meg at her most super-energetic, so I wanted to hold off until we were back in London to see if the change was sustained. It very obviously is. She is asking to get out of the buggy much more often, and going longer and longer until she needs a break. She is also swimming for much longer than she was. I am so, so pleased and so relieved to see the impact on her (the squirrels are maybe less so). Her weight has been edging up a bit recently, and we all know how crucial it is to keep that down, and it will be so much easier with her being so much more active.

Here are a couple of vids from the seaside, so you can see her moving, and a pic of my precious girl, just because...
