So my roommate has a dog she's always been very bonded with me since I am home all day with her she sleeps with him but about 30 minutes ago she started whining ans Scratching at his door which she never does so I let her out and she's constantly pacing and sniffing and barking at nothing..... Any one have any ideas as to what her problem is? I am slightly bleeding but did checked me today so it may be from that......
