Most Chi's ears go up and down until they are done teething. Tucker's were up for weeks, and then one or the other of them would go down for awhile. They both have been up now since he was about 6 months old.
I got Snuffy when she was 2 months old and her ears were down...the breeder told me to rub them upward and they should come up when she got older. I did just that and she's 3 months old now and they mostly stay up :wave:
My Lola's ears were erect when I got her at 11 weeks. They flip-flopped for months-mostly 1 up and 1 down. She had surgery almost 2 weeks ago,and they have both been down since then-but when she sleeps they are almost always up :dontknow: She is on my lap right now and 1 is down and the other is sideways. I heard that whatever way they are by a year is the way they will be permanetly-Lola is almost 15 months so I guess she's destined to have 'undecided' ears :wink:
