Holly is a 2 yr old Lab that we just adopted 2 months ago. She absolutely hates other dogs. When we walk on the side of the road she gets super excited and it's hard to hold her back, like she wants to go play. But when we get too close she will growl and lunge at the other dog. She just really doesn't like getting too close to them. She is absolutely perfect with people it's just the dogs. I'm scared to socialize her because of how she reacts. Is there anything I can do? Or is it just a phase in her life. She was just spayed and hasn't been introduced to another dog since her spay, so not sure if that will make a difference.
