That's so strange. At least to me. The vast majority of people here have some sort of animal, mostly dogs and cats. IIRC there are something like 70 million dogs here in the US. There's such a huge population that there are millions of homeless dogs living in animal shelters that adopt them out, hence why I'm weird about dog breeding. Here in the US there are so many dogs that need a home that it's irresponsible for the average person to breed their dogs. It's also why most dogs here are neutered or spayed.They are generally regarded as "unclean". And kids sometimes chase them with sticks. You should see some of the women with cats. They literally freak out when they see any. Definitely not a good place for a dog or cat to be. People keep their animals indoors and I rarely see dogs, if expats do own them they usually try and find accommodation outside of town with plenty of space and security to roam around in.
All the dogs we've had have been "networked" dogs, i.e. knowing someone who has had a litter and needed someone to take the puppies off their hands.
The population is so big because most Americans love dogs. My family has tons. My parents have owned over 20 dogs total in their lifetimes combined, along with ducks, a chicken, and a wolfdog. People here seriously love animals. Right now my mom has the two terriers (Rat and Decker as mentioned) and wants to find another Decker now that she knows what they are. My dad has a Miniature Pinscher mix and will be getting a Catahoula Leopard Dog soon. My mom's girlfriend has a Silky terrier. My cousin has two Dobermanns. Three of my friends have Pit Bulls. My mom's neighbor has six Labradors. Her other neighbor has a Boxer-Lab mix.
Speaking for the US, but the same applies to most western nations.
