Anthony Volgmann, 30, volunteered as a dog walker and performed sexual acts with the animals while they were in his care between January and September last year.
He then posted the images on the internet, making them available to the public, resulting in a second charge of corrupting morals, the Moncton provincial courtroom heard.
Volgmann, who was found fit to stand trial last month following a psychiatric assessment, must follow several strict conditions as part of his probation.
Judge Jòlene Richard has banned him from owning any dogs, working or volunteering with dogs, or going to places dogs might be, such as dog parks, dog shows, animal shelters and veterinarian offices.
She also ordered Volgmann not to own or access computers or smartphones with online access, except if at work or under supervision.
The sentencing follows a joint recommendation by the Crown and defence.
