Does anyone have a GSP? How well do so in an environment with other dogs kennel whike work 8h a day?

I wonder if GSP easily suffer from separation anxiety. I have 4 dobes Currectly. Joring scooter and I love my sled dogs, but only have a dog, a good left. 1 does not like running, 1 only had major surgery for a torn ligament in his knee and 1 is increasing with bad hips. I have 2 garages and a large house on 3 acres of fenced land. My two garages they have become dog kennel that I draw from my human society and train them before sending them back to help find homes. Would it be feasible to have a GPS in this type environment if run for an hour during weekdays and 3-4 hours during the weekend? Moreover, they often take holidays and sometimes work outside the home for a few days at a time in which case half of my dogs go to a kennel because they have separation anxiety and the other half are cared for by the mother of my 65 years of age. Thank you very much for their advice on the matter!

My GSP is kept in a cage most of the day, but let me go running in our field and take a walk occasionally. She does well in a drawer and has no separation anxiety. David S: He / She said that the GSP does not GSD! Shorhair German pointer.
