Dog question

I threw sticks for Lola for 45 minutes straight,no breaks. My arm will fall off before that dog gets tired.


I should tell the whole tale. It was a nice warm day so I took her to the river and started by throwing them 3-4 ft in. The dog had never swam nor been in water so I gradualy extended the range until she walked out and lost her footing!
She popped back up, sneezed and swam for the stick. There was a moment when I thought she had gone too far into the river and dangerously close to the strong currents out there. She powered her way back and it's funny to see as her neck/up is well out of the water. Even her front shoulders are clear! All I could think was no wonder I have such troubles holding her to my side. Very powerfull dog for all of 65 lb's.
