i feel i am in the same place as you
Layla's babysitter is a dog trainer and she said to wait until layla is over a year to bring a new member into our family... i say go for it! i want to get another for layla... i want her to have company.. but then the other part of me doesn't want her to feel left out when everyone oos and ahhs over the new puppy... it's a big issue in our house but i think i'm leaning towards another one... good luck... keep us updated!
