My Chloe is 4 months old. I don't have a problem with caring for her when she gets her first heat. My question is though, does not spaying bring any health problems or complications for her own well-being? She is not around any male dogs. Also, how does pregnancy work in dogs, can she only get pregnant during heat.. or she can get pregnant at any time? Since she is small I would definitely not want her to get pregnant. I have heard spaying changes their personality. I wouldn't want to put her through procedures that she doesn't need, I only want to do it if it's for her own well-being. If someone could explain this to me I would appreciate it. I want to be prepared to know what to do when her heat comes. Thank you!
