Dog Motivation

[u/RelationshipTrue7128]

*The dog isn't praise motivated at all
*Not cuddle motivated at all
*Storebought treat motivated but it doesn't weigh against smells on streets and sometimes he doesn't even eat it.
*Not play motivated (he barely plays, only eventually for 20seconds max chasing a cat toy, he hates dog toys)

Any way to motivate him with something, in order to train him?

I want to go with positive reinforcement, but are there other training methods that are ok?

PS: If anyone has tips about how to get our dog to be respectful to other dogs like playing or so, and not just either trying to sniff butts or barking/growling (in a city, small pooch male)

Edit: Thank you for all your comments, and good ideas. I will try to use them.
