We recently rescued a chiwawa who's, the vet says, about 1.5 years old and has clearly been pregnant before. When we first got her she would act worried and cry often; pretty normal for a dog in her situation. That faded as we trained her not to and she began to get comfortable.
After a while we noticed her playing with rolled up socks and a few of our other dog's (Boston Terrier) furry toys. So we bought all the dogs their own toys. Immediately, our other dogs began the ceremonious destruction of their's; while Bean, the chiwawa, looked as if she was living a horror movie.
Since, she has become burdened by the toy; she seems to worry about it constantly. She acts strangely around it seeming to hurdle over it and lay on it oddly. She's also started making her kennel bed with her mouth crazily at night when they go to bed. Earlier tonight we took it away on the DL. She's looking around for it and crying too. Is it possible she could be confusing this store bought toy as an offspring?
I've been around bread dogs and have seen where a mother will try to continue to care for a dead pup; is it possible she's remembering her motherhood?
