Thanks all...
Thanks all of your replies. Thanks avalonandon, I thought of the method u suggested too, but unfortunately I stay alone, my dad comes once in a while so will have to arrange a training session with him.
I think I will need some help to handle both dogs in training certain behaviours. I just got her not long ago, when I got her, she was very insecure, refusing to walk on leash with me poo n pee in the house, very sensitive to cars/motorbikes/people passing by not to mention dogs etc. Now she is getting much better, but still she barks/growls at people passing by or at a distance, in short she gets distracted easily. I am waiting for her 3rd shot of vaccination before taking her out for training. She used to play rough with my rott, my rott is real gentle, they just can't stop playing with each other at first and most of the time my dob just get too excited and cause my rott to yelp in pain. Now I got both of them to stop when I say "no", she also eats gently from my friends now, used to eat like a machine. Much better now. I think all these problems was due to the breeder, neglect and lack of socializing when she was young.
I don't know y, she seems to be able to push my buttons easily. Sometimes i take both of them out together but instead of doing their business they play with each other, that's not play time, play time is when I take them to the park in the evening. My rott is getting stronger day by day, so it will be hard to control both of them alone, especially when I have to pick up their poo on 1 hand and the other holding the leash, so I resort to take them out 1 by 1. Taking her out first is much easier, my rott just whines a little then she stops when I walk away but when I return to take the rott out, she still barks. When she sees other dogs she barks and her tail was pointing down, got to build her confidence level, my rott is very confident, a happy n super friendly dog but my dob is the exact opposite. It's a challenge to build her confidence and make her happy. She frowns all the time. She's got a character.
I know they are attached to me, I bring them along wherever I go, they are very well behaved minding their own business when I am driving. I am going to work on clicker training. Any of you guys have good results from clicker training?
