I have an adorable 10 month old male Pom. "Teddy" He has been very friendly and well behaved! He adores my six grandkids, and loves playing with them. The grandchildren have friends in the neighborhood and they always play together in our backyard! Teddy has been good with them, however he has recently become aggressive to one of their friends. He barks nonstop and will growl and try nipping at this 8 year old boy if he get too close! I'm not aware of this child harming Teddy in any way but he does have a tendency to tease him. I'm afraid the child may get bit. What is the best way to handle this? Should I crate Teddy when the friends are over, or ask that they play someplace else? Any suggestions? Please
