Surgically induced tumor seeding was diagnosed in 8 dogs and 2 cats. All animals had histologic confirmation of neoplasia in an unusual location or pattern, and a history of surgical manipulation of a similar histologic-type tumor at the site of seeding. Highly malignant carcinomas (8/10 animals) were the most common tumor type. Seeding occurred secondary to a variety of surgical procedures and in the face of various adjuvant therapies. Seeded tumors were recognized from 2 to 30 weeks after the causal procedure (median, 6 weeks). Survival times after the causal procedure ranged from 15 to 131 weeks (median, 45 weeks) and 8 of 10 animals died or were euthanatized because of seeded tumors.

To evaluate vestibulovaginal stenosis in dogs.


Retrospective study.


18 dogs with vestibulovaginal stenosis diagnosed between January 1987 and June 1995.


Signalment, results of physical examination, and diagnostic testing, treatment, and outcome were analyzed.


Mean age at initial examination was 4.6 years. Problems reported by the owners included signs of chronic urinary tract infection (6 dogs), urinary incontinence (4), failure to mate (4), signs of chronic vaginitis (2), and inappropriate urination (1). One dog did not have evidence of a clinical problem. Vestibulovaginal stenosis was detected by means of digital vaginal examination (18/18 dogs), vaginoscopy (17/17 dogs), and positive-contrast vaginography (9/10 dogs). Bacteria were isolated from the urine of 11 of 15 dogs. Twelve of 18 dogs were treated. Manual dilation (4 dogs) and T-shaped vaginoplasty (4) were less successful than vaginectomy (2) or resection of the stenotic area (3). Four of 6 dogs with signs of recurrent urinary tract infection underwent surgical correction, and none of these dogs subsequently had urinary tract infection. Three of 4 dogs with urinary incontinence responded to medical or surgical treatment for sphincter incompetence or for ectopic ureters.

Clinical Implications—

Surgical correction of vestibulovaginal stenosis is indicated in dogs that have mating difficulties or signs of recurrent urinary tract infection or chronic vaginitis, but stenosis is probably an incidental finding in most dogs with urinary incontinence. Vaginectomy and vaginal resection and anastomosis are the preferred surgical options. (J Am Vet Med Assoc 1996;209:1889–1893)

To evaluate indications for and complications, efficacy, and effects on renal function of unilateral nephrectomy in dogs with renal disease, and to evaluate the role that scintigraphy had in the decision to excise a kidney.


Retrospective case series.


30 dogs with renal disease that underwent unilateral nephrectomy. A comparison group of 12 dogs with renal calculi that underwent renal scintigraphy but not nephrectomy was included.


Indications for nephrectomy included renal or ureteral calculi (n = 10), renal mass (8), chronic pyelonephritis (5), perirenal mass (3), severe hydronephrosis and hydroureter (3), and renal hypoplasia with ureteral ectopia (1). None of the dogs were azotemic before surgery. Renal scintigraphy apparently influenced the decision to perform nephrectomy, because in 14 of 16 dogs that underwent nephrectomy, the affected kidney contributed ≤ 33% of the total glomerular filtration rate, but in 6 of 8 comparison dogs that underwent nephrotomy, the affected kidney contributed > 33% of total glomerular filtration rate. Complications of nephrectomy included oliguria (5) and organ laceration (2). Mean ± SD final serum creatinine concentration for 16 dogs alive at least 6 months after nephrectomy was 2.2 ± 1.8 mg/dl. Three dogs had chronic renal failure of undetermined cause at the time of death. Nephrectomy did not completely resolve the underlying disease in 13 dogs. Renal function was evaluated in 6 dogs 2 to 3.5 years after nephrectomy and was impaired in 4. None of the dogs were anemic, azotemic, proteinuric, or hypertensive. Survival time varied depending on the underlying disease.

Clinical Implications

Multiple factors contributed to the decision to perform nephrectomy. Unilateral nephrectomy resulted in few serious complications and was not detrimental to the remaining kidney, but did not always resolve the underlying disease. (J Am Vet Med Assoc 1996;208:2020-2026)

To examine the prevalence and context of one-health conversations between veterinarians and clients in companion animal practice.


A random selection of 60 companion animal veterinarians; a convenience sample of 917 interactions from Southern Ontario, Canada. Of these, 100 audio-video–recorded interactions including 47 of 60 veterinarians were randomly selected for inclusion in this study.


Audio-video recordings were made of veterinarian-client-patient interactions between November 2017 and January 2019. A researcher-generated coding framework was developed and used to assess the prevalence and content of one-health topics communicated during veterinary appointments.


Of the interactions assessed, 60 were preventive care and 40 were health problem appointments. Further, 78% (78/100) included at least 1 discussion related to one health. One-health topics included zoonoses (28% [28/100]), animal behavior (25% [25/100]), illness/disease (20% [20/100]), activity level/exercise (16% [16/100]), nutrition (16% [16/100]), dentistry (6% [6/100]), body weight (3% [3/100]), animal welfare (3% [3/100]), dog/cat bites (2% [2/100]), cannabis (2% [2/100]), and aging (1% [1/100]). Zoonotic diseases were mentioned in 65 appointments, 28 of which evolved into a one-health discussion. Antibiotics were discussed in 27 appointments, none of which were discussed in relation to one health (eg, antimicrobial resistance).


Findings suggest that one-health topics are raised within most veterinary appointments. Opportunities exist for more comprehensive one-health conversations between veterinarians and their clients, particularly in relation to zoonotic diseases and antimicrobials.
