Why dogs can be your best friend

I had dogs for many years and they are all different.Like people they have thier personaltys.I have gotten dogs from the pound and got them off death row.Some really thanked me for it in being trusting and faithfull like a good person friend.I had one dog who was a runner and if he seen the door open hed run off and youed have to catch him,little jack ass.Then i had a dog who was a true guard dog "born that way"she stoped any person walking thru my yard .She would stand on the edge of my yard and if someong came close shed bark and then escort them of my property.Bad part of her was she was a dog fighter i got from the pound.they lied to me saying she loved all dogs and other animals.I have a dog now who is a person in a dogs body.hes fun and thoughtfull ,watchs over me when im haveing a bad day.Hedoes the dog stuff too like eating cat shit when were walking if i dont see it before him.long story short they have the best things people have without the bullshit some people do.yup i live alone
