I love dogs and have owned a dog for the past 8 years. I currently have two dogs, a Black Lab (Monte) and Jack Russell Terrier (Olive). I've had both of these dogs, 3 and 4, respectively, for the past four years, and previously owned a Boarder Collie. Olive experiences high anxiety, which shows with aggression, so I am familiar and work well with dogs who have anxiety and aggression (as long as it is not towards me, lol). For a thirty minute RUN, you will get a minimum of 3 miles, depending on your dogs speed. For a 60 minute RUN, you'll get a minimum of 6 miles. I would also be willing to negotiate taking your pet hiking in the mountains. I also carry treats with me on my walks to try to help dogs stay present and well behaved and will work with them on commands such as sit, heel, leave it, drop it, etc.
