Hi all, I've recently bought a 14 week old female Rottweiler cross Bullmastiff pup. We've had her for about 10 days now. I've got two problems that I'm struggling with. The first is house training. Because the weather was good when we had her, we've basically left the back door open since we had her (as long as we're in the house and awake). If the back door is open she does her business outside 100% of the time and has done since day one. If the back door is closed she goes by the back door with no warning at all. I'm trying to figure out the best way to get her to let us know that she needs to go out so that we don't need to continue leaving the door open all the time. The second is sleep (or just being left alone at all really) With all my past dogs, I've been a firm believer in just leaving them in the room they're going to sleep in and ignoring the crying for 2-3 days until they get used to it. This time, that absolutely will not work. I've given her some of my old clothes for a familiar scent, I've given her a hot water bottle, a ticking clock, left a radio on and just about anything else I can think of. She will quite literally stay awake for the entire night scratching and banging on the door and digging up my kitchen floor. This has been going on since we had her and we're about to start having serious issues with the neighbours because of the noise. Yesterday I borrowed a crate from a friend and introduced her to it over the course of the day, when night time came, I left her in the crate in the living room where she's most comfortable and then left her. She was exactly the same and in the end, in the interests of preserving both my sanity and relations with my neighbours, I took the crate upstairs into my bedroom. After about a minute of whining she settled and slept. I'm not a huge fan of dogs in the bedroom but if it works I can live with it, but it gives me a problem with house training again. I set alarms for every three hours through the night to take her outside. At the first alarm I picked her up and took her outside and waited 20 minutes. She just lay on the floor and went to sleep. I put her back in the crate and half an hour later she'd done (both) her business in the crate. I could probably think my way around the problem if I could get a few hours sleep but I'm currently dead on my feet. I've kept dogs all my life and never had such difficulty. Any advice on where to go from here?
