I've known dogs since before I could walk and talk. I am about 11 weeks old in my first Christmas pic. Before I could walk I was crawling and communing with dogs. From age 10 on I had responsibility for my family's dog. I've been to dog training classes at two different locations with two different dogs over the years. I'm familiar with "control" collars and working with them as well as more modern positivity methodology. I'm also a relatively big guy who at 6 ft 2 in and 220 lb feels comfortable in saying I can walk your two large or giant sized dogs. I know my rates are higher than most but I pride myself on my ability to work with any household dog and I always work with your dogs alone as some of my charges need individual attentions. I never mix those from various owners unless both owners are in on such a plan. Regarding my rates, an overnight is 12 hours typically something like 6:00 p.m. to 6:00 a.m. or 8:00 p.m. to 8:00 a.m. if you have a customer request that doesn't fit Rover's buckets we can certainly discuss if you wish to contact me. If needed I also have house sitting references available.
