Vets were shocked this week after X-raying a dog and finding a toy plastic arrow inside her that was a big as she was!
They said they didn't expect Betty to survive, but the plucky pup pulled through.
So have any of your pets had a lucky escape?
Perhaps they've eaten something they shouldn't have, or went on an adventure and were lost for a few days.
Maybe they had a medical problem too and needed a clever vet to save them.

"Once we went to our grandparents and when we got home I went to check our rabbits because there had just been a thunderstorm. When I got into the garden I saw two of our rabbits had escaped. My mum and dad came in and I had found one of the rabbits and was keeping a close eye on him. Just as we thought that the other one had escaped from the garden I found her. Later on we found out that they had eaten a lot of foxgloves which are poisonous to rabbits so we thought they were going to die, lucky for them they were fine."
