She is a 7 yr. old beagle/shepherd(?) mix who was rescued at 3 mos. from some guy who threw tools to shoo her away.
In the past 1/2 year or so, her trembling and whining and nervous pacing is really escalating for things like thunderstorms, fireworks, and now riding in the small motorhome. At night, now, if a storm rolls in, she gets nervous, jumps off bed, whines a bit, pants heavily, paces around, trembles, and maybe settles on bathroom floor. Similar behavior as RV starts moving down hwy: she used to lay at my feet in the floorspace between passenger seat and dashboard. Now she sits panting, occassionally a slight whine, pacing back and forth in RV, and sometimes shivering.
She's always had a startle reflex and/or fright response to something sudden or new, and on leash, this often meant hackles up and often an aggressive snap at another leashed dog.
Is it common to see a fairly rapid amplification in fearfulness at her age? We are starting to think some type of pills may be needed for future RV trips and maybe on fireworks holidays (others in neighborhood setting them off).
