I would try a couple of visits with the independent groomer first, just a get-to-know-you type of visit with treats and petting, then a bath and brush-out. If the groomer can schedule Jazz for a quiet time in the day, that would be even better. My Quinn is leash reactive with other dogs so the groomer does him on her one late night per week after the others have gone home. She will gate any dogs that happen to be there late in another room so there is no contact.
Please don't litter. Neuter your pets!
