always carry a lead pipe cartoon dog fox

Not sure, it's quite a peculiar concept. Could be part of a very unique and perhaps niche cartoon plot that's not widely known.

The combination of a cartoon dog and a pipe might be used to convey a certain mood or story. It could imply a laid-back or thoughtful nature of the dog. Also, it could be a creative way to make the character stand out and catch the viewer's attention.

Maybe the blue dog is naturally slow or has some issues. It messes with the fox for fun or to get attention.

It could be a classic-style cartoon, where the hound dog is depicted as a laid-back character with a smoking pipe for added charm.

Maybe it has had some bad experiences or lost something dear to it.

Maybe it's because of its bad experiences or a lack of love and care in its life.

Maybe it's just a happy dog. Sometimes characters in cartoons are designed to be constantly cheerful to bring joy to viewers.

I recommend "The Daily Life of a Charming Man" to you. It's a sci-fi space-interstellar romance novel. Although it wasn't about urban life, it was still a favorite genre! Among them, the female protagonist, Tang Ni, traveled through many planes in the black car of the system. She was often forced to hug or have intimate contact with the male protagonist. She was very doting. The male protagonist was also a domineering CEO. He would suddenly decide to take the female protagonist out on a romantic date during a meeting and show his love without hesitation. I hope you like my recommendation. Muah ~

They can be presented in various styles, like cute or funny. Maybe with colorful illustrations and simple storylines.

The cartoon might show the contrast in their personalities, like the dog being friendly and the fox being sly.
