Old gal Mindy / by Randy Ortiz

So I just found out my sisters dog Mindy (Beagle Harrier) has a tumor. She is 10 years old, and always has been SUPER loyal to the fam and never did anything bad (surprising for a dog). She's been moping around the house crying and tearing. Drinking lots of water and has to go a bunch of times in a day. I wonder how that just comes about, granted she's a bit old and all. The operation is 3k-5k, and in this time of resession...it might hurt the wallet a bit more than other times. My sister said that some people just have their dog live with it (Kind of cruel), or put them to sleep (Also cruel)...what is a dog owner to do in this scenario?

I have no idea what I would do if it happened to my Puggle. Thats my hairy son!
