I agree....i started out with Raisin & Mia. A coupler would be hard to use unless they are walking well without. Give Meadow time to learn to walk and learn your commands that you use with Alina. "Let's go", "leave it", "heel"...etc. I kept mine on two leashes, now they walk in tandem. I've worked with Lily since we have had her and can now walk the three of them easily.
