Hello! Nice you chose this theme as I am a HUGE animal lover! Dont give milk to dogs :D They cant digest lactose, but maybe yours is immune by now..
I personally have a dog and a horse, who get along very well! Lexi, our Amstaff is 2 and a half and Dextro, the youngest member of our family is a 13 month old stallion.
They both are used to each other and Lexi is trained to never walk behind the horse. I will post a video soon when Lexi is walking with the leach of Dextro and go for a walk. Greets!
