* Excited whimpers or yelps: Dogs often get very excited when they see or smell a treat, and they might let out little yelps or whimpers to express their excitement.
* Panting or licking their lips: These are signs of anticipation and are not necessarily crying.
* Tail wagging and jumping: These are also expressions of happiness and excitement, not sadness or crying.
Dogs don't cry tears of joy or sadness like humans do. They communicate their emotions through body language, vocalizations, and other behaviors. So, while your dog may be making noises that sound like crying, it's more likely just a happy expression of their excitement for the treat.
