thank you for your replies.
Yes, Brandy has been like this since she was younger - now she is 5 years old - she was uncontrollable and she has a lot of 'energy' - when she was a puppy she never rested she was always 'dancing' around. Now, due her age is less hyperactive.
Also, I admit I don´t take my dogs to walk everyday, so they are locked many hours, they don´t run as dogs should do, our house is smal and also I have a lot LOL, so some days I take the little ones and the other days are the big ones! I accept my responsability here due to keeping the dogs and not giving them in adoption when we could do it, bt Brandy has been an special case and the time passed and we decided to keep her.
With my other dogs is very different, I go out with them and they don´t get crazy when they see people around and they obey me when I talk/shout to them firmly. I "read" them very well, Brandy is a 'time bomb' hehe.
I have an eppisode one month ago where Brandy bite my neighbor´s dog and so I decided not to get her out of the house anymore. So yes, maybe she is indeed sad due to that and that´s why she is angry.
And, we have trained her two times, and the instructor told us how to order her many things but she gets crazy when people rings the door, and also when we touch the window, lol. She doesn´t hear us if she is attacking to protect us.
Definetly there has to be a decision as soon as possible.
Yes, we have to decide this for the best of the other creatures here.
uf many decisions within these days! I´ll let you know what we did, we are still talking my mom and me about this situation, also with the vet, she knows her and she also had suggested that also due to seeing my mom very worried.
I will keep you informed!
Thank you a lot!!!!!!!!!!!
