Females will often go through a stubborn streak and you may have a time with them. It is expected. They are female! I had one girl that at about 15 months to 21 months just decided too that she hated the table. We were in handling class one week acting like a pro and then the next week her hormones kicked in and she decided she hated the table. My trainer even asked me if this was the same girl. LOL My girl finished in 3 weekends (back to back) with an extra major. I could not believe how fast she finished! It blew my mind! I love the ones with this mean streak! And so do the judges - because they usually love the ring and show off when coming back up to the judge. Love'em!!
Just let her know who's boss and you can work with a table lower to the ground and give her treats and then work your way up higher, till you are using the regular table. She will get it.
