Near the end of September,
we hiked Dominguez Hill to Escalante Cross in SPanish Fork! I think the pups enjoyed it because they were carried 99% of the time. When they say dog friendly, I don’t think that applies to chihuahuas, it was a bit much for them! Pretty good workout with some steep up & down, but relatively short & doable! There were signs posted everywhere warning of a bear in the area, so I was glad it was a pretty well trafficked area.
