Fellow dog walker has said she's been approached in a park by someone who's dog is coming into season and liked the look of her male dog. Other owner wants one litter before spaying and friend wants her dog to have fathered a litter before neutering.
I'm not against breeding family pets, but neither owners intend to health test their animals and haven't planned it out, just winging it. Every time I mention health testing or plans for if anything goes wrong I get laughed and told I'm being silly.
