right now we have Reese and Savannah in one kennel since Reese is still little....well she was littel. She isnt so little anymore since she is at 30 pounds-Savannah at 50. So with Reese going through one of her growth spurts and now that she is starting to pack some weight on, would it be best for me to get a seperate kennel for her? They love sleeping together, but i dont want to crowd them. Also i dont trust them to be outside the kennel at night. Savannah has started to regress with her house training since reese came home. I think she figures "reese gets away with it so can i" i dont want to wake up to a mess so to be safe i kennel them. these are the measurements of the kennel 42 L x 28 W x 31 H". Should i get another one so each dog will have one? or would it be ok to keep them both in this one?
