As of January 1, 2022 a series of German animal welfare laws took effect, including a ban on tethering, a ban on the use of spiked or pull collars, a limitation on the number of litters a professional breeder may have at a time, and a requirement that breeders spend at least four hours per day with puppies in their care. The ban on pull collars even applies to dogs who are used by law enforcement. Accordingly, forty-nine Berlin police dogs who are trained to subdue individuals already have been placed on an imposed suspension of duties pending effective alternatives to pull collars.
