Help Cosmo remove his cancer

Hello all. I recently received some devastating news. My precious fur baby Cosmo has a lump on his chest that was diagnosed as cancerous. He needs emergent surgery to cut out his cancer. His vet states there is a strong likelihood that if he gets this surgery he will go on to live a cancer free happy rest of his life. This surgery is going to cost $3,500.00. I don’t have the means to immediately come up with the funds to make this happen for him. The longer I wait to have this removed the bigger the risk of it spreading. I am a strong believer in living within my means and taking care of my responsibilities. I am a single mother of a middle schooler, high schooler, Oskie a main coon cat and Cosmo a pit bull mix. Cosmo is the youngest of all my responsibilities. He is just over a year old and has brighten our lives much more than I could’ve ever imagined. He loves life and is beyond the best dog I have ever met. We adopted him from the Boulder human society. Everyone that meets him falls in love with his spunky attitude and tremendous joy he finds in everything he does. He even LOVES going to the vet and as long as he gets his biscuits he doesn’t even mind getting shots. It has absolutely crushed me that I don’t have the means to fix him. If you could find it in your heart to help us we would be enterally grateful. If you do not have the means to help, I understand completely, your thoughts and prayers would be much appreciated. Thank you so much for caring, listening and helping. From the bottom of my heart, thank you in advance.
