I think you are perfectly entitled to put the onus on the vet as the medical professional Luckylegs . Children will believe what a doctor says and if there is any anger after the dog has gone, it is better if it not directed at you for having taken the decision.
Sadly vets usually put the ball in our court. When I had to make the decision for Hattie I asked my vet not what I should do, but in all honesty what she would do because even if it is the case that sometimes something can be done (like with Noel Fitzpatrick’s Border Terrier) I do not believe it necessarily should be done if you see what I mean.
Sentimental, but then when it comes to my dogs I am that person.
The story of the Rainbow Bridge tells of a lush green meadow just "this side of Heaven" (i.e. before one enters into it). Rainbow Bridge is the name of both the meadow and what links it to Heaven
According to the story, when a pet dies, it goes to the meadow, restored to perfect health and free of any injuries. The pet runs and plays all day with the others; there is always fresh food and water, and the sun is always shining. However, it is said that while the pet is at peace and happy, they also miss their owner whom they left behind on Earth.
When their owner dies, they too arrive at the meadow, and that is when the pet stops playing, turns, sniffs at the air and looks into the distance where they see their beloved owner. Excited, they run as fast as they can, until owner and pet are once more in union. The pet licks its owners in joy while the human looks into the soft eyes of their pet—who might have been absent on Earth, but never absent in their heart. Then side by side, they cross the Rainbow Bridge together into Heaven, never again to be separated.
