Looking for a foster home

It breaks my heart to ask this but is there anyone in the Parry Sound/Mactier area who would be willing to foster a 2 1/2 yr old Australian Shepherd/Border Collie mix? I was living in Nobel but due to unforseen circumstances, I had to relocate to Barrie. Oliver is miserable here. He has gained so much weight, doesn't want to play, and is just not himself. We have been in an apartment for the winter and it's just taking the life out of him. I am currently working in Mactier at a golf resort and want to save up to move back to the area. I am just as miserable in Barrie. I do not want to lose Oliver. He's my whole world. He's such a sweet boy and extremely smart but since being cooped up in an apartment for the last 6 months, his temperament has changed. Hes just over 2 yrs old and looks like hes 10-11. I'm looking for someone who has land for him to run. He needs proper excersize and until I can find a place up there, he's stuck in the apartment while I'm at work. 8 hr shifts plus an hour each way for the commute is extremely unfair and bordering cruel to him. I will pay for his food and anything he needs. If someone can be please help me I would be forever grateful. I don't want to lose him. I'm the stubborn type that never asks for help but I'm putting my pride aside because I want Oliver to be the dog he's supposed to be. He's used to having all this space to roam and be free. This is slowly killing him. I just need some time to save up and move. So I'm begging, can someone please help me?
