Hi, so I have a one year old weim and an electric bike. I can easily run him at his ideal pace for as many miles as he needs (huge blessing!). Sooo...what is ideal?? We just ran 3 miles in maybe 15 minutes. He's looking at me like he could do another 10, but I also don't want to kill my dog plus, do I need to stop and give him water?! Haha He pants hard cause he's running hard... can someone who knows the breed well, please advise? Thank you all!
