I emailed two breeders in the Houston area: Apollo Goldens and Xcelerate Goldens. Both are recommended and have really nice dogs. I heard back right away from Apollo who informed me of upcoming litters in Feb and May. I emailed Xcelerate over a week ago and then again on Friday. I have yet to get a response from them. Is this a bad sign? Should I just try and call via phone or move on because the communication is lacking already? Any experience in this department for you guys?
