So Vic and I noticed that every time Kiwi is around new dogs, whether at the dog park or just meeting them, the hair all along her spine from her neck down to her nubby tail stands straight up. Does anyone else have this happen to their pup? It normally takes it a while to go down, and even still the hair closest to her neck stays up. Is this is a sign of being threatened or simply excitement? We were just wondering because she came into contact with her first stroller tonight and it happened as soon as the stroller rounded the corner.
