yes I believe Kali understands us..she will come and put her paw on us if she needs to go outside and do her business, or if she is hungry she will do the same..she knows her 'squeeky' toys, mama, daddy, car ride, trails, walk, i could go on.. lol! she also knows the difference if i am putting my hiking shoes on(means we are going for a walk) or my dress shoes for work (means mama's going to work)...if we say 'who's there?' she will bark, if we ask her 'what time is it?' she knows its her time for playing at the park....she knows what 'nails trimmed', 'teeth cleaned' and 'tub time' is too!!
