Not really. I don’t recall anyone advising that you should add glasses and a beard to your dog, who has recently taken up smoking! Although it;s your dog, so I guess you can do whatever you want.
You’ve got to think of your target audience and your potential market though. Having a dog in your logo is niche enough… but having a smoking dog that wears glasses and has a beard, is really going to narrow down your potential customers. Probably best to drop those elements.
