This reminds me of a situation we have here at home. Although much less of a problem.
We have a neighbor who has a boxer/rot mix. His name is Bud. I love Bud, he's a sweet boy, but I don't want him around my girls! I'm so afraid that Daisy will nip at him and he will instictivly turn on her and hurt her or worse.
Our neighbor, who is a friend of my husbands' says he tries to keep him in his yard, but Buddy ends up over here all the time!
I've taken Buddy back home several times, hubby had taken him home several times and everytime we talk to the owner and ask him to PLEASE keep Buddy in his yard. The next day Buddy is back.
The other day hubby took Buddy back and knocked on the back door and said, "does he belong to you?" (jokingly) the neighbor replied, "was her in your yard again?" Hubby said, "Yes, just as Tammy was bring Abby and Daisy out and it scares her!" Neighbor says, "shoot him"
Can you believe that?
Hubby said, "Nope, I think I'll just shoot you" Good Grief! Just shoot him.
Poor Buddy hasn't done anything wrong and we will not shoot him, unless we are confronted with what the shi tzu's owner was...even then I wouldn't...I don't have a gun anyway..
I'm glad to hear that the little Shi tzu will be OK. I was just thinking about Jinny the other day
RIP sweet Jinny.
