Speciation ("Micro" evolution) is: When a human and a human have a child, the result will always be a human but have a combination of the genetic traits of it's mother and father. Same thing with all of the different breeds of dog, they're all genetically compatible.
...but that's not really what speciation is. Speciation is the development of new species through evolutionary processes. As with your dog example, different breeds are just groups within species.
Evolution ("Macro" evolution) is: When a human and a human have a child, somewhere down the line the result will not be a human and not be able to reproduce with humans, sharing different genetic material than its species.
The key phrase here is "down the line". What you term "macroevolution" is simply microevolution across many generations, and it is probably closer to what speciation really is, which we have observed. There is no distinction in science between macro- and micro-evolution.
Evolution (macro) is a theory, unobservable, unrepeatable, speculation, and extrapolation.
Evolution is not mere speculation. It is a scientific theory: one that is substantiated by facts. Speculation does not involve considering factual evidence.
Consider FAQs about the theory of evolution from http://www.talkorigins.org/ for information regarding how evolution is observed.
