Pet Care Needed - Full-time / Part-time

We have one adult female named Tulla who we need some care for on the days when my husband and I are both working. This would be 1-3 times per week around lunch time. We usually walk her at a local park to get some energy out. She barks at strangers but is very lovey once she knows you. No aggression issues and a pretty good leash walker. She will probably pull towards other pups wanting to play but ignores most people on walks. Tulla is also extremely food-motivated so bringing treats will win her over.
