My next door neighbor uses on for their 4 yr old giant lab. When I walk snickers I'm always really cautious b/c he will follow us along his yard. Well, 2 days ago, he just walked right past the invisible fence to come see us. I've met the dog b4 (without snickers)but this whole thing was SOOO scary b/c the owners were not outside!! It all turned out ok though
But, IMO, I would definately not chance it b/c
1. Someone could steal your baby
2. He could walk right through it if he really wanted to
3. Other animals can get in
4. I always worry too much about whats flying over head. I don't let mine out unsupervised.
