Aw.
R.I.P Buster

Its really sad when a dog dies, my dog died when I was really young.
He was reallly friendly as alot of dogs are, and was out running about one day and a girl on her bike kicked him and he hit her (not bite, hit with his nose) and she hit her knee of the bike.
And then she went crying to my parents, and my dad put our dog down.
Then we found out about an hour later, that she was being OTT about it, but it was too late.
Like you said, at least Buster is with his mum now.
I wonder if Pet Heaven and Human Heaven are like combined?
I would love that, it means people get to see their pets again.
