On the last day of April, I learn that it had been Animal Control Appreciation Month (
LinkedIn).

County and city Animal Control both appear to rely heavily on Computer-Aided Dispatch, as intake records often appear on the animal shelter's website while the animal is still on the truck.
In the jurisdiction of the City of Las Cruces, Animal Control Officers are part of the police department, and can be heard communicating with Central Dispatch on "channel 2" (
EDACS 02-122,
P25 11354). On EDACS, there is an "LCPD Code/AC" channel, 02-127, but I've never heard Animal Control on it, and it's referred to on air as "codes". (Codes Enforcement is also part of the police department, but they will call for a patrol officer in the event an arrest needs to be made.)
