Many Thanks to everyone, Lizzie went to Rainbow Bridge this morning.
She had had a restless night and her tummy was swollen, I was actually worried about her.
She did wake up with her usual tail wagging and she had fresh chicken for breakfast.
The vet came to the car to sedate her and I sat next to her and loved her until she fell asleep. The only bad thing was the sedative I gave her before we set off didn't touch her, she was up and watching her 'dad' go into the vets, she wanted to make sure she wasn't missing anything. The vet came out and gave her a sedative, she still didn't go to sleep so she had to give her a 2nd injection. That's just Lizzie she was a little fighter and very obstinate when she wanted to be which is apparently a beagle trait, so she was my little miss up until the end!
We just took Guinness out for a run in the car and now we are all home with heavy hearts BUT I know we did the best we could for her and she knew we loved her very much. I now have to make sure Guinness doesn't grieve too much.
Again , many thanks to everyone.
