My westie 13 and a half just died without warning. I came in from shopping and he was pleased to see me tail wagging jumping up. He then went in the garden. Came in and his legs collapsed I went to get him up and my sister said he is foaming at the mouth. His head lifted but he didn’t get up his breathing was shallow. The vets were busy - my sister said he has gone. I listened to his chest he was dead. Since I bought him home at 12 weeks he has slept on my bed. He had been with me when I lived alone. My sisters husband just came home and we’ve buried him in the garden. Had no time to say goodbye... so sad
