Yes I do in some circumstances, but only when I know a dog fairly well.
Initially your dog won’t know me and will see no reason to come back to me just because I am calling his name.
I need to be confidant that he is trustworthy with other dogs and people, that recall is established and he is responsive to me. There needs to be an unquantified period of time for him to adjust to me and each dog is different. Only when I feel he is ready will I let him off lead.
Owners need to give permission in writing and accept full liability in the event of straying.
With regret, all entire dogs will only be exercised on lead (extendible leads are provided).
