我隻狗想做乜？

你隻狗狗平時係咪係你房訓咖?
你平時唔開冷氣既話 道門係咪一樣會關上?
其實你隻狗狗係咪慣左自出自入?
你將度門關上佢冇左呢種自由所以先有呢個行為呢

其實佢抓得度門 最有可能性就係想度門開你試下唔好關實度門 留條"拿"比佢(佢隻手要抓得開度門)睇下佢反應係點

我都有狗狗，佢地有時真係似一個小朋友，好得意～～

照我估計..你隻狗可能係想你同佢出街玩掛...因為有一次我隻狗都同你而家0既情況一樣..攪左好耐都唔知佢做乜..後尾我嬲嬲地就趕左佢出房...冇耐佢又係到抓我房門.跟住我諗佢可能係想同我玩..咁我咪試下囉..點知我一叫佢出街玩嚕..佢就咬住d狗玩具飛撲過黎我度..諗返都覺得好攪笑....

May be it stole something and put it in your room and it scared you to discover this secret. You should follow it quietly and open the door on purpose so it would go in and you can see what is the reason.
it can also be some strange reaction after it saw something.

佢可能好掛著XXX啦......
(XXX = 某人/某狗)
