Exodus 11:7

7 But not a dog shall growl at any of the Israelites—not at people, not at animals—so that you may know that the Lord makes a distinction between Egypt and Israel.

Exodus 11:7 In-Context

5 Every firstborn in the land of Egypt shall die, from the firstborn of Pharaoh who sits on his throne to the firstborn of the female slave who is behind the handmill, and all the firstborn of the livestock.
6 Then there will be a loud cry throughout the whole land of Egypt, such as has never been or will ever be again.
7 But not a dog shall growl at any of the Israelites—not at people, not at animals—so that you may know that the Lord makes a distinction between Egypt and Israel.
8 Then all these officials of yours shall come down to me, and bow low to me, saying, "Leave us, you and all the people who follow you.' After that I will leave." And in hot anger he left Pharaoh.
9 The Lord said to Moses, "Pharaoh will not listen to you, in order that my wonders may be multiplied in the land of Egypt."
