I'm sorry that your question wasn't answered in a timely manner. There appear to be multiple concomitant disorders. I'll address them as you presented them...Epiphora (excessive tearing) in just one eye isn't likely to represent allergy but, instead, an irritant that found its way into that eye, trauma, or perhaps an anatomical disorder involving her eyelid(s) or eyelashes - entropion
, distichiasis, ectopic cilia, e.g. Pruritis (itchiness) involving the paws is pathognomonic (specifically indicative) of either atopic dermatitis
(allergies to environmental allergens such as pollens, molds, dust, and dust mites, etc.) or food intolerance. Neither allergy is reliably addressed with antihistamines; instead, a short course of a corticosteroid such as prednisone is usually prescribed for atopy
and a presumptive hypoallergenic
diet is fed to address a food intolerance. Her yelping, reticence to jump up, move, or be handled about her rear end suggests musculoskeletal or spinal pain. Her vet will need to carefully palpate her in an attempt to localize the pain. X-rays may be recommended. Finally, "accidents" in a well-trained dog indicate a urinalysis in an attempt to identify a urinary tract infection. If not found, behavioral inappropriate urination is considered and we also have to consider that medical problems elsewhere in her body can cause behavioral changes in elimination. Behavioral modification should never be attempted until all medical causes are eliminated. Please respond with further questions or concerns if you wish.
