Have you ever talked to a women (human) who has had a full hysterectomy due to illness or other reasons...they are still feminine, and can have sex. We humans (and perhaps dolphins and apes) are the only species that have sex for pleasure. To convert our ideas of sexuality and place them on dogs is not very bright.
Do you really think the Government has the time/resources or money to put into regulating ownership and breeding
Wow, we can barely take care of the people (education, poverty etc.). You will never get rid of puppymills, the only thing that will stop them is when people stop paying money for pet dogs. No money, no reason to breed...simple.
Spaying and Neutering should be mandatory for pet animals. It does nothing to change their personality, and actually takes the biggest stressor out of their life...not being able to reproduce with the proper "equipment" is much more unhealthy and stressful for a dog/cat. Casterating also prevents many unwanted problems in the future. Also, males that are intact and not able to breed can suffer problems due to this.
If you were to compare wild animals to our domestic dogs/cats then that is unrealistic. In the domestic world we have cures and vaccines to prevent puppies and dogs from dying. In the wild survival of the fittest decides who survives to pass on their genes...not all wild dogs survive past puppyhood. This helps keep the population from getting crazy and out of control. But, having said that, having domestic dogs living in amongst humans we cannot allow these diseases/parasites/bacterial infections/starvation to cull the weak naturally. We cannot allow diseases to run loose throughout a human civilization, it puts we humans at risk.
Do you know how hard that is for most people? I have seen male dogs scale high fences to get to a female in heat. At one kennel I worked at a Shepherd in boarding chewed through chain link fence to get at a female Dalmation in heat. I know of children who have almost been attacked by going out the front door of their home and having intact males outside fighting (that was me when I was a child
). Most people "think" that when the female is bleeding that's the time to keep the female away, when it's after they stop bleeding that they can be bred. I can't count the amount of unwanted pregnancies with pet dogs I have seen that happened for this reason. Some females have silent heats as well.
Dogs can also have split heats, my female Tori had 4 heat cycles last year. Not fun, blood dripping in the house. Yeah, great fun. After this litter the breeder will allow me to have her spayed....I can't wait. Poor Tori goes through such stress during the heat cycle, the other females become bitchy towards her, and she usually get down in the dumps when in heat.
Perhaps it is different in Countries where over population gets reduced due to disease and starvation/shooting. But, here in North America while there are some sad situations etc. on the most part a big majority of pups/dogs are feed, sheltered and vaccinated against disease. Dogs that are well fed will produce bigger litters than domestic dogs in poor countries. What may be fine in a poverty area or Countries that have once a year dog shootings then it may be fine to not alter your pet. Yes, in most underdeveloped Countries when the population of dogs gets too high, they shoot all the loose dogs they can find. That is probably how the Phillipines takes care of over population. It won't work here
That's how they control rabies and distemper.
