It all started about 4 months ago when I begged my parents to buy me a dog. They said i could only i was willing to do all the work. And i PROMISED them i'd do all the work. that night when we purchased my dog (which is a mix between a chihuahua and a weiner dog.) i started to regret it because he kept whining, but then afterwards he got used to the place and i was happy i didn't try to sell him. But the thing is my dad lives in Hong Kong and he visits my family during summer and winter break and during those time we'd always go out and the dog would be left alone ( we'd bring my dad to places for him to visit and we'd be gone for most of the whole day roughly from 12:00pm to 9:00pm) at first we tried indoor potty training which seemed to fail for whenever the dog pooped in a certain area he wouldn't urinate there again until we pick the poop up ( during the time when he poos we're still out) so when we don't pick up the poop he eliminates someplace else like on the cement floor. But afterwards when my dad left and i was starting school again, i tried outdoor potty training which was looking great except i had no control to wake up and bring my dog out and when i woke up i'd be late for school. ( i couldn't ask my family members because my parents wouldn't let me because i PROMISED them) but i often do manage to get my dog out to urinate. During noon my brother would take my dog out (he's in university) and after school i'd take him out and before i go to bed. Training him with sits, come, etc. has not been very progressing because im having a bit of trouble in middle school myself and rarely have time for myself. And since it's the winter break my dad has come to visit again for a couple of weeks again and the dog is still not properly trained. The whole family's going to be out again leaving my dog alone. I really don't want to go back to indoor training because i live in an apartment and the odour is horrible when the dog poops. My dog is currently 6 months old and i'm willing to wake up at 8:00am and try to bring him out right before i leave the house, im also willing to bring him out first thing when my family comes back from wherever we are but i need advice on what to do, what my schedule should look like, and around what time to train my dog, how to train my dog (sits,come,his name, etc.),my brother's not willing to help much. and apparently my brother said that our dog is as useless as a homeless dog.Whenever i have time to train my dog i use a positive attitude. I usually do have time to play with him but always a bit lazy to train him. I haven't abused my dog in ANY way.I'm willing to make a change but i really need advice. Any advices anyone?
