We put her down that same day, a Sunday, but i woke up, went to give my dog her food and found her whining and gnawing at her back legs,(she was fine the day before), and we called all the vets from Fresno county and one was opened on a Sunday, only one. we took her to the car and to the vet. we sat and waited for what felt like years, and they told us she was paralyzed in her back legs(paraplegia) because of a blood clot. is that possible, and why would that of happened? we had to put her down, one of the saddest moments in my life, but im wondering if that could have been what really happened and if there were better routes to take. i am also wondering if there is a way to prevent that from happening on my current dog. i will answer any questions. Thanks.
