jquery errors

Built this site a while back and have had no issues. Now there are several errors in the console causing the nav menu to not show up and images in the slider. I’m at a loss at what is causing them. There have been no new plugins activated and nothing has changed in the structure of the site. If you’ve got any suggestions I would greatly appreciate it.

site with errors – manymutts.com

as well, manymuttssf.com – the same theme, same company but no errors.
