Hi, just got our new lab pup (this morning), as it was very sick in the car i wont be able to take it on the school run (as i planned) so will have to leave it at home with my other dog, i dont want to leave them together, is it ok to crate the puppy whilst i'm out? I dont want it to freak out at the crate as he is not used to it and i want the crate to be a positive thing. What should i do? i cant crate my other dog as she bites the bars and hurts her mouth, i might be able to put my other dog in another room but she's likely to get stressed. She likes the puppy but is still a bit wary when it tries to play with her.
