Help me avoid pyometra

Hi my name is Charlotte... im a beautiful 2 years old black pug, i love to play with my chubby mom and bark at other dogs, but lately i've been feeling very very bad; for the past month i've had nothing but a terrible infection and no amount of antibiotic has being able to help poor me. finally my vet has warned me that i must retire my small uterus and renounce to be a future mom otherwise i will develop pyometra!

PD: Hi im Esteban and im the owner of Charlotte and her mom Bambam who is currently 8 years old, as you can see im trying to raise the funds so my best friend can get its surgery. it makes me really that she needs this surgery because i wanted one day to have the children of Charlotte, but her life is more important than anything else o and here is a pic of my two beautiful ladies.

Thank you very much.
