Yes, purposely breeding animals (sometimes importing negative traits) for the purpose of having a companion is ridiculous. Puppy farms, pet stores, kennels all exist because people want an animal. Purebred dogs are inbred to the point that they develop rare types of disease and genetic conditions.
: "As they deliberately manipulated the appearance of dogs to create or accentuate physical characteristics that were considered aesthetically pleasing, like the flat face of a bulldog or low-slung eyelids of a bloodhound, breeders also created physical disabilities. The excessively wrinkled skin of the Chinese shar-pei causes frequent skin infection; bulldogs and other flat-faced (or brachycephalic) breeds such as the pekingese have breathing problems because of their set-back noses and shortened air passages."
