We got Abby and Daisy only 9 days apart! Daisy was 2 and Abby was 10 wks. Daisy was rehomed due to a couple getting a divorce and nobody being able to keep her and we had been planning on Abby for 4 months, it just happened that way.
I love having 2! They play together and keep each other company when we can't take them with us. I think the closer in age you get them, the better. I wish Abby and Daisy weren't nearly 2 yrs apart.
I'd love to have another one, but I really couldn't afford to properly care for another one and spoil them the way I like to if I were to get another one. If money were an issue, I'd have 3!
