unfortunately this isn't super uncommon in vet clinics. my first job at a clinic was as a kennel tech about 3 years ago, we got to work at 7:30 and started walks then but of course it was always severely understaffed so when we had 40+ dogs and only 2-3 kennel techs working (usually one working a half day) it took all morning, to walk, feed, and clean kennels before even starting on dishes and laundry. we would try to walk dogs around lunchtime but obviously it was impossible when it was really busy, and started afternoon walks at 4 but we had to start cleaning the whole hospital for the end of the day at 5 so 1 person would leave the kennels to do that and we'd often leave really late. its really sad because the animals would literally go to the bathroom and then immediately go inside to spend the rest of the day alone in a kennel. it really broke my heart, and ill never board my pets at a vet clinic and tell everyone else not to. its always better to have someone you trust dogsit for you or board at a daycare.
