A cause I care about needs help

Hi my name is Tumble, I am a 6 year old cockapoo! Today I did 250 ball throws, which doesn't sound like too much, but I was completely exhausted by the end of it!
I am on a mission to raise money for the charity Shelter, which help millions of people who may be homeless or who struggle with bad housing. In times like these it is extra important that we all make sure that everyone has a  roof over their heads and they can feel as safe as possible, so help me to make a difference! 
In every pound donated to shelter, 21p is used for fundraising and 79p is giving directly to helping people!
