Got let go of my volunteer work in an animal shelter...long story short I have no idea what happened...I did as I was told...yet the owner was convinced that I was somehow mistreating the dogs... I did as I was told thanks to other volunteers, co workers, and a dog walking orientation. The lady who did it was very nice and helpful. Unknowingly she told us apparently somewhere where we weren't supposed to go and I got in trouble via the director...and true I did bring my own dog since I saw that another co worker brought his 12yr old beagle and another co worker brought in again another beagle in so I thought everyone could. maybe she has something against mutts idk (even though half the shelter are mutts) above is a picture of my awesome dog and I think that if the owner of the animal shelter had just played with him a little bit maybe she wouldn't of let us go...I loved it at that shelter and I loves those dogs and cats like they were my own personal pet... I played with them, hugged them, kissed them, donated food, toys, my time, gas money and love...more than they were probably getting...and yet I get told to leave and not come back... I feel bad for those animals... 😭😭😭😭
