First off, I have had a horrible morning.
It was my first morning to sleep in, in a long time. I had razzled the dogs up and was taking them out to pee and all. I have cats, lots of em and they are my babies. ANYWAYS. I was letting them potty and then out of NO WHERE this huge Husky lookin something can running around our pool deck. (No one was hurt) except my CAR! He jumped all over my car trying to get to my cats. We do not have an outside dog anymore. *he passed away due to cancer*

so as of late we have had a lot of trouble with my neighbors dog coming up here trying to kill the cats, the chickens, and I'll be d-word if they try to kill my dogs.
Now to the advice part.
We are planning to get 2 doberman pinchers in the spring. Should we keep them inside at night and out during the day? Since the only time I have had trouble with her dogs is during the day. How do I make them... run off the other dog?? And I am sure there are people on here who are against ear clipping. If you are, do not comment. But what age do you do that? And how long, what's the cost? I am sure most of you will probably be like... hmmm.. We don't have a doberman. But with any dog you get their ears clipped. Around about the cost of that and all. We had a pitbull before who was natural but I want the dobermans to look as scary as possible! LOL.
Any advice/tips will be greatly appreciated.
Thanks everyone <3
