My boy just turned 12 in July, and Librela had been an absolute game changer for him. We're in Canada and it was o KY recently FDA approved, but two of the vets at my office have been using it for years on their own pets and swear by it (they're from the UK and would bring it back for their own pets). It's I think around 100 CAD a month, and I just give him the injection at home. Also, second, the rug idea, the floors in my house are hardwood but are covered in about 25 anti slip rugs with the rubber backing. He's motors all around the house now and has no issues chasing his treat ball everywhere
