OOC: Since you've had these particular dogs for some time, I'll allow it, and assume you gave the command on your initiative. Any new animal companions you get will be a little more hastily trained...
Gertrude: The dog cautiously steps forward, hunting. She pauses, sniffing, under the apeture. Growling, she looks up, but seeing nothing, she looks back at Norynth for further instruction.
Suddenly....
Lizards: A large, scaley lizard bursts out of the hay in the loft, leaping all the way down at Grimbard. (OOC: Norynth, this is now your initiative). Before it even reaches the ground, Norynth's crossbow clacks and a bolt streaks through the air, narrowly missing the creature and sticking into the wood ceiling. The lizard directs a fierce bite at Grimbard, but its teeth fail to penetrate his armor.
Titus: The terrier barks in surprise, and growls. She stays protectively at Norynth's side.
Grimbard, you're next, though I think I can foretell your action...
edited for clarity...
