Hi everyone. First time on the forum, a new member. I'm not so sure if someone else has posted the same condition before - but all help, advice, ideas welcome (and needed!) She is my beloved Purds. She is a 10-year-old standard white poodle. I love her more than words can describe. She is a very lively, curious and stubborn girl who is very intelligent. She loves her walkies and exploring the surroundings for a long time. Very often she would wander off following a smell or a sight of an animal in the forest. She has been the most energetic, incredibly active dog who has walked miles and miles without any sign of tiredness or slowing down. Until just 5 days ago. Last Sunday we had big cuddles, belly tickling, loads of fuss and attention. Her usual self when nothing matters more than just the two of us. Then this Tuesday two things became very noticeable - her sight deteriorated (up close she couldn't see where the treats were - she could only smell them) and her walking. She became wobbly, leaning towards one side or the other, exceptionally lame to the point of being reluctant to come down the stairs or even get in the car. She is usually the very first one to greet me when I walk in through the door, she is literary flying down the stairs as soon as she hears my voice. But not now, not in the last 5 days. She is not as lively as much as she used to be. The vet said cataract on both her eyes, but arthritis on both her legs (due to the lameness). Is it really possible for arthritis to develop or even progress that fast? I didn't notice anything looking like arthritis or joint pain before these 5 days. Can the vet be wrong here? I know she is 10, but with no previous signs... The vet recommended synoquin which we have ordered online but she doesn't seem like herself more and more every day. I feel like it is something else, and my main fear here is a stroke. Anyone any experience similar or advice?
