Answer:
Thank you for your question. This is the answer from one of our vets:
I’m sorry to hear you are having difficulties with your neighbor’s dog. If talking with the dog’s owner has not been successful, the Havahart Spray Away (
http://www.fosterandsmithaquatics.c...) can be helpful in deterring animals from entering your yard, but it would also spray people and your own pets if they enter into its field. There are also electronic repellants (
http://www.fosterandsmithaquatics.c...) that may keep the dog out of your yard. Again, they would also affect any of your pets, as well. Perhaps one of these options would work for you. Good luck.
