Hi ive had puppies before from 8 weeks and training has gone good . This time i have taken a rescue labrador at 5 mths old . She is house trained , and she cant sit on command but gets up straight away , she has no other training , just wanted to know 2 things , she sleeps in a crate at night do i need to put water in with her , he previous owners didnt but is all night too long to go without water , also is recall training the same as if she were a small puppy as she has never been let off lead and both my other dogs were , not sure if at 5 mths this is still possible to train
