Lost Dog- small black- tan and some graying (Tukwila)

Small dog found in tukwila, near Cristal Springs Park. Two days ago he showed up inside our gate- small easy to get under. No collar. Sweet but scared, and upset. Clingy, house trained not leash trained. Used to jumping on beds. Acts like an indoor dog but understands to stay outside. Injured leg, no cuts seen. Missing his family. 15832 51st Ave S Tukwila, WA 98188
