I 've had experience of taking my small sized dogs like poodle for 2.5 years old. I also had experience of taking care of my cousin's medium sized dog husky for nearly a year. I'm currently training my 3 months old toy poodle of all basic skills, now he's learnt: 'sit' 'sitting by my heel',' recall',' drop it' ,'leave it' ,'fetch', 'bring things back'. I'm very patient with training dogs, it's a game for them as well as for me. I really enjoy taking them for a walk, playing games with them, looking after them, it's one of the wonderful things happening in my life living together with dogs.
