I have a three and a half year-old papillon who tends to be a worry-wart and is a real talker--not so much a barker but whines a ton to communicate her excitement and happiness as well as fears. Recently she's been acting very strange and I'm trying to put the pieces together to figure out what's going on. She was just diagnosed and is being treated for an ear infection, as she's been scratching her ear, shaking her head and just seemed out of sorts. But more worrisome is her strange accompanying behavior in the last few days. She does not want to get on the grass to go potty--she adamantly keeps coming back to the porch. Today I put her on her leash and kept walking her through the grass encouraging her to go but she wouldn't go and even started shaking. Even stranger, for the last two nights when she's on the bed she is on-alert not closing her eyes to go to sleep, but looking at the bedding and appearing to track things, sometimes she gets up to check the spot she's been watching, then she'll move to a new location and start doing the same thing again. It appears as if she's hallucinating--it's very unnerving behavior--we don't know what to make of it but can tell she's very concerned about something. We don't think she's sleeping well and are sure this is contributing to her grumpier-than-usual-barky behavior during the day. We just started her ear drops but this was happening beforehand so I'm sure it's not medication related. Also about a week ago we stayed in a hotel where we discovered fleas--we checked out and tried to get all the fleas off our dogs and bathed them, but since our dogs do not typically have fleas we are wondering if she might still have a flea on her and this is the underlying link to her strange behavior. I am planning to give her another bath today. Has anyone else dealt with similar behavior issues or have any ideas as to what might be worrying my sweetie? Thanks for your thoughts!
