Dogs DO speak, we just don't understand what they're trying to tell us... they speak with their body language. Dogs cannot speak English because their mouths and tounges are not formed for the English language. Why can't humans speak dog? Same reason.
strangely enough, with the right training some dogs can learn to speak a limited amount of words, but it will be a while before we can train them to speak in full sentences.
plus, the dogs probably dont know what they are saying
Dogs have a means to communicate, but do not have the brain development for learning and using spoken language.
They can speak.

You can say "speak" whenever you hear the dog barking and give it treat and praise. The dog will soon associate the treat and praise to the word and action. Then the dog will speak on command because they know what the sound is telling them to do and they want a treat.
