Need help with some diagnosis
Hello. I am in the UK so refer to my times as BST(British Summer Time)
Today, we had to do the hardest thing and put one of our dogs to sleep. This was at 7:30pm. However, I'm needing some help or some advice as to why she got so sick. So in the morning. She was absolutely fine, to the point where she was her normal self and playful as ever.
Yet at around 3pm. She started to be sick again and again. 664
Right after one another. The first time was her breakfast and from then on. It was like.. flem. So from then onwards, I also noticed her breathing was getting shallower/struggling to breathe. So taking her to the vets and she didn't improve at all. In fact she got worse and to the point where she was declared critically ill.
So I'm looking for advice as to what this possibly could've been as the vets weren't able to disgnose it. Especially since she was fine in the morning and just instantly turned from 3pm onwards to us having to decide to let her cross the rainbow bridge.
Could it be poison or something? As the back gate to our garden was open 2 days ago super randomly as nobody goes in and out it unless doing some gardening etc.
Very heartbroken at the sudden loss.
She was a 9 year old Yorkshire Terrier. 664
