Sims 4 has an amazing lack of Harnesses for dogs. One of the things I feel it needs are Job vests.

I'm referring to:

Service dogs
Police dogs
Medical dogs (different than a service dog)
Sled dogs
Military/War dogs
Sniffer dogs (used to find drugs, bed bugs etc.)
Hunting dogs (some have vests)

There is no one vest or harness for any of these dogs so google image around and use those for inspiration ^.^

Each type has a different vest, some more different than others. Specifically I'd like a Police Dog vest, Military Dog vest and Service Dog Vests.

I will ony ask for one service dog vest, though If anybody is willing to take the time to make different kinds, I encourage you to search Amazon (where many types are sold) and Google Images to find a few styles and try your hand at making them ^.^

Police dogs and Military dogs usually have unique special collars and tags:
Example of Police dog's Police badge and pocket for ID
Police Dog's collar with POLICE spelled out on the back
Example of a Police Dog In training collar ( not sure if real police collar)
Military Dog's Tags
Lastly, this is an example of a real Military Dog wearing a typically Military Dog Collar. You can also see very similar tags as shown above. The tag seems to remain pretty consistant.

It would be nice if somebody could make those too.

I encourage anybody who wants to try any of the mentioned things to go ahead and try it! The more variety the better! Just because one person has offered doesn't mean you can't try doing it too! I look forward to seeing what you all come up with!
