help bouncy get back home
Why this petition matters
bouncy is a (we are pretty sure) a cross german shepherd. A homeless man was trying to sell to my boyfriend and i. We tried bringing home shoes and a bottle of water instead, an oldish man was sitting near us, we asked if we could still take the dog and he was hesitant but the man convinced him to give her to us.
she was weak, hungry and thirsty, full of ticks and flees.
i walked back to bens house holding her in my arms feeling she was weak and exhausted. i phoned my mom and eventually she had got a hold of a vet that wanted to take her in.
when i got into the car she started howling and it broke my heart
she followed me around everywhere, jumping all over the place so i called her bouncy.
this petition is to convince my parents to let bouncy come back home to me because i miss her so much
