My Border Terrier Mije was trying to show that young whippersnapper that there is life in the old dog yet, by chasing my daughter’s Jack Russell around my garden. The whippersnapper was trying to be a bit frisky with the old girl and she wasn’t having any of it. Would you at 77 yrs old (doggie years). This is in real time and not speeded up. I was pooped just watching them.
