I have a huge 115 lb. bouvier des flandres and I had him microchipped because his breeder and I had a disagreement. I was afraid she would steal him and I knew this was the only way to ensure his identity (I haven't had any problems with her since I nuetered him. He is show quality). He also jumped the fence before we put an electric one in. He loves to chase squirrels and cats. I am considering doing this to my poodles too, but haven't for financial reasons. I have a 3 year old and a 7 month old, so they are expensive too. I am all for it, just don't do it to me! I went into to pay a bill at my city last week. They had a sign on the door to check there if you lost a dog. They only keep them for three days then put them down. I almost volunteered to be a contact but have to talk it over with hubby first. I don't think he will go for it though. I don't think three days is long enough. Why can't they at least take them to the pound. Don't they have a better chance of living longer there?
