I can't believe those Fockers would tell you that. I have a beagle/shepherd mix. They told me she was a nervous peer! Hurrrumph! Maybe it was because she was scared of the mean lady who did the temperment test.
She's never peed out of nervousness or excitement since I got her over a year ago.
Todd, if you like a dog and you are willing to make the time commitment, you will have a great dog.
