I think she did ,She said they were in the middle of a Blazing Row ,and she just wanted to get away ,so I think in a temper she shoved/kicked the dog who she said was in the way
Because she was so riled up ,and giving her the benefit of doubt I think the Shove with her foot was harder than she thought it was ,which probably made the dog Yelp ,so her denying she ''Kicked'' it is True in a way as in she didn't pull her foot back and swing at it deliberately
However despite the above ,Admitting that you Hate the Dog ,and didn't want it near you on the bed etc , is just Bizarre and the woman has serious issues and needs professional help being Jealous of your Boyfriends Dog
