In Search of Anyone Who Has Been Through Something Similar
My dog is a 13-year-old spayed female Italian Greyhound/Rat Terrier mix, approximately 10 pounds, and I'm hoping to connect with anyone who has experienced something similar, particularly following a carotid body tumor diagnosis, aspiration pneumonia, or chronic regurgitation that has persisted despite treatment.
Timeline
May 2026
She tripped in a hole, fell, and hit her head. Immediately following the fall, she developed acute and evolving symptoms, including:
Inability or unwillingness to get up
Loss of appetite
Excessive drooling
Tongue dysfunction and facial nerve paralysis
Regurgitation
Coughing
Initially, it was suspected that she had sustained a neck injury from the fall. She was treated with prednisone and also received acupuncture and laser therapy, but continued to deteriorate rather than improve.
She was subsequently treated with antibiotics and anti-nausea medication without significant improvement. Interestingly, the tongue dysfunction and facial nerve paralysis appeared after antibiotic treatment was initiated. Her veterinarians did not believe these signs were due to an allergic reaction.
As her condition worsened, a sedated oral exam was performed, which revealed a mass near her epiglottis. A CT scan subsequently identified a right carotid body tumor. The CT also noted inner ear disease.
She later developed aspiration pneumonia and was hospitalized briefly before undergoing emergency surgery to remove the tumor. Pre-surgical testing did not identify any additional masses, and her prognosis was considered favorable.
July 14, 2026
She underwent surgery to remove the carotid body tumor. Discharged with antibiotics.
Post-Surgical Course
July 19, 2026
Just days after surgery, she required emergency hospitalization due to ongoing aspiration pneumonia and concerns regarding her ability to swallow safely.
She stabilized and was ultimately discharged but developed significant hyper-drooling, tongue dysfunction, regurgitation, and anorexia. She remained on:
Metronidazole
Clavamox
Baytril
until mid-September, with ongoing weekly follow-ups with her veterinarian.
Neurologic and Ear Findings
July 30, 2026
She was referred to a dermatologist to evaluate the inner ear disease identified on the CT scan. Surgery was recommended as a treatment option and it was suggested that the inner ear issues could explain some of her symptoms.
On the same day, she had an emergency consultation with a neurologist. After evaluation, the neurologist did not believe her symptoms were neurologic in origin and did not recommend surgery for the inner ear disease as he disagreed with inner ear disease being the cause of her presentation.
August 6, 2026
She was hospitalized again on an emergency basis for aspiration pneumonia. Due to the ongoing swallowing dysfunction and poor overall outlook at that time, euthanasia was recommended. A follow-up appointment with the surgeon was advised before making the decision to euthanize.
Several days after this hospitalization, she experienced a spontaneous and dramatic improvement in all symptoms that lasted several weeks.
August 11, 2026 - Surgical Recheck
At her post-surgical recheck, it was noted that the facial paralysis and tongue dysfunction had largely resolved. However, concerns remained regarding a lingering swallowing issue.
She was prescribed:
Cisapride
Sucralfate
Cerenia
September 21, 2026
She required another emergency hospital visit due to:
Elevated temperature
Lethargy
Refusal to eat
Chest radiographs and bloodwork were reportedly normal, and the veterinary team was unable to identify a clear cause for her presentation.
She was prescribed a 7-day course of:
Clavamox
Baytril
Following this hospitalization, she experienced another period of minimal clinical symptoms that lasted until approximately October 9.
October 5, 2026 - Endoscopy
An endoscopy showed:
Mild esophageal stricture
Esophagitis
She was prescribed:
Cisapride every 8 hours
Omeprazole every 12 hours
Sucralfate every 8 hours
Three days later, she deteriorated again and has now been regurgitating daily, typically 3-4 times per day; at the time of this posting her symptoms have been clinical for 9 consecutive days.
Current Symptoms
Regurgitation of white foam, sometimes mixed with food
Wet-sounding throat noises
Difficulty breathing through her nose
Recurrent swallowing issues
Intermittent coughing
Gagging
Drooling
Persistent hoarse or altered bark
Feeding Management
Prior to all of this, she ate a raw diet from 8 months of age.
Since symptoms began, we've tried:
Home-cooked meals (following a cancer-diet recommendation)
Freeze-dried raw food
Small, frequent meals
Pureed food
Feeding from an upright position similar to management for megaesophagus
She appears to like eating in an upright position, but it has not significantly reduced the regurgitation.
One encouraging aspect is that, despite the ongoing regurgitation and other symptoms, she has maintained a good appetite for the past several weeks and remains very interested in food, particularly while on acid-reducing medications.
Questions
I've explored the possibility of megaesophagus and have also wondered about myasthenia gravis, although neither has been strongly pursued by her veterinary team to date.
What continues to puzzle me is that her original cranial nerve-related symptoms largely resolved by mid-August, yet the regurgitation, intermittent respiratory signs, aspiration concerns, and persistent hoarse bark continue to wax and wane.
Has anyone experienced anything similar, particularly:
Persistent regurgitation after carotid body tumor removal?
Swallowing dysfunction that fluctuates dramatically?
Aspiration pneumonia with periods of near-normal function?
Myasthenia gravis presenting primarily with regurgitation and aspiration?
Another diagnosis that might fit this pattern?
Any similar experiences, diagnoses, insights, or suggestions for additional testing would be greatly appreciated. Thank you ❤️
TL;DR / For Those Who Didn't Read
13-year-old Italian Greyhound/Rat Terrier mix.
Symptoms began immediately after a fall in May 2026 and included facial paralysis, tongue dysfunction, drooling, regurgitation, coughing, and refusal to eat.
A CT identified a right carotid body tumor, which was surgically removed on July 14, 2026.
She subsequently developed recurrent aspiration pneumonia and required multiple hospitalizations.
By mid-August, the facial paralysis and tongue dysfunction had largely resolved.
Endoscopy showed only mild esophageal stricture and esophagitis.
Despite improvement in the neurologic signs, she continues to experience:
Daily regurgitation
Swallowing difficulties
Wet throat/breathing sounds
Intermittent coughing
Persistent hoarse bark
She has had two periods of near-complete spontaneous recovery, followed by abrupt relapse.
She currently has a good appetite and remains eager to eat.
Specifically looking for experiences with:
Persistent swallowing issues after carotid body tumor surgery
Aspiration pneumonia with no clear cause
Myasthenia gravis
Megaesophagus
Pharyngeal/laryngeal dysfunction
Vagus or cranial nerve injury
