I am trying to find a dog trainer to work with my little terrier mix dog who climbs our 4 foot tall back fence. I don't want to have to list her in this site because she went in an adventure. She is 4 years old, weighs 12 lbs and is a mix between miniature schnauzer, Yorker and Italian grey hound. We have tried everything. Our yard isn't really set up to use an underground fence. I don't know what to do anymore and don't want to have to chain her in a fenced yard. At my wits end.
