The great thing about beagles is that they are one of the most friendliest, loyal, and compassionate breeds of dogs out there. They are the perfect dogs for people with small children and other animals. Sometimes they might make aggressive gestures or growl but it's very unlikely for them to actually be violent. My Lucy beags growls and howls at the mailwoman but that's just her trying to sound tough, when she approaches Lucy will just sniff her and let her be.
