Please help! I have a female, 13 year old Yorkie - about 8 lbs. She got out last night and we found her this morning. We then noticed she is in heat. We aren't sure if a dog could have gotten to her. She isn't spayed so from what I've heard, that's what we need to do. I don't know where to go that won't cost me a fortune. Her vet says it will cost up to $350 and I don't have that kind of money right now. Where is a good, reasonable price to take her? Or does anyone know what I should do. Thanks in advance.
