The biggest thing to realize is that condition x is not caused by (fill in the blank). I've seen drugs/vaccines blamed for things all the time that have no relation. When Trifexis was being blamed for killing dogs, a local news story came out and they interviewed a dachshund owner saying it killed her dog. The dog was paralyzed a few weeks after getting a dose. Now this breed is the poster child for disc rupture and is in all likelihood what happened to that dog with zero relation to Trifexis.
Specific to Librela, it has been in use in Europe for a few years. If it was causing all these deaths/side effects, we should know about a lot of it already. I personally have our 15 year old dog on it. He has received 6 doses now. 2 weeks after his fifth dose, he had a vestibular disease episode. Old dog vestibular disease is pretty common and I suspect is what he has. I don't believe it was related to the librela, and in fact gave him another dose a week ago. He's been more mobile the last 6 months than the prior 2 years on other arthritis meds.
I think with the internet/social media, things get blown out of proportion (see the 'new' respiratory disease in dogs a few months back). It is best to talk to your vet and see what makes the most sense for your dog.
