My dog is like that some times as in crying for no reason..but I noticed last night that since she has been getting close to my husband when hes not around she misses him..shes such a daddys girl and also b/c since I get out at 5 from work hes already home by 3 so its like hes the first face she sees..I think she also needs more time with me...I feel bad and I also feel like crying when I see her crying..lol...lol..
