Sorry, but no, that's not remission. Using Caninsulin is tricky when you get into those lower numbers which is why we recommend one of the gentler, longer lasting insulin's like Lantus, Basaglar, Levemir or ProZinc.
With Caninsulin, you do have to be more careful about how low you shoot but as you gain more experience and understanding about how it works, you gradually shoot lower PS's to try to get Nacho to spend more time in green than blue.
Where in the world are you? Since you're using Caninsulin instead of Vetsulin, I know you're not in the US. (they're the same insulin, just called Vetsulin in the US)
