I scanned your post and then read some responses and then went back and read it again because, um, what kind of weirdos come unglued about llasas, a Doodle puppy and a GSD pup? Four GSDs, rotties, Dobies come running into my yard, yeah, I'm going to be startled. But, no offense, were talking two little mops and the goofiest dog on the planet (Doodle) as 3/4s of this scary dog pack?
I'd be more scared of a pack of cats.
Still, yeah, be careful. You have crazy neighbors. Gosh, where I grew up nobody ever called anybody about a neighbors dog unless there was dead livestock or blood going on.
