Spike you have some valid points. One of the reasons people do worry about placing animals with single is because they do want to party and often dont realise the time and energy that goes into raising a dog or any animal
having said that I know for a fact that good breeders check the people single or married, childless or with children.
If you have always been around dogs and cared for them I am sure that this would show in your attitude
Some of the people on this site had dogs before marriage and their partner had to accept that the dog even slept with them roflmao.
