Abstract

OBJECTIVE To characterize congenital laryngeal paralysis (CLP) in Alaskan Huskies.

DESIGN Prospective case series.

ANIMALS 25 Alaskan Huskies with CLP.

PROCEDURES Data were collected for each dog regarding signalment; history; results of physical, orthopedic, neurologic, and laryngeal examinations; esophagraphic findings; treatments; histologic findings; and outcomes.

RESULTS Severely affected dogs were profoundly dyspneic at birth or collapsed after brief exercise; less affected dogs reportedly tired easily or overheated with minimal exercise. Mean age at initial onset of clinical signs was 6.4 months. Blue eyes, white facial markings, and oral mucosal tags or tissue bands were noted in 23 (92%), 19 (76%), and 13 (52%) dogs. Neurologic examination revealed signs of mononeuropathy of the recurrent laryngeal nerve but not of polyneuropathy. Histologic examination revealed neurogenic atrophy of the cricoarytenoideus dorsalis muscle but no polyneuropathy. Eight (32%) dogs underwent unilateral cricoarytenoid lateralization, resulting in substantial clinical improvement, including ability to compete in sled dog races. Without surgery, 4 (16%) dogs died of asphyxiation, 10 (40%) had spontaneous improvement of clinical signs (but insufficient improvement to race), and 3 (12%) remained affected. Results of pedigree analysis suggested an autosomal recessive mode of CLP inheritance, with variable penetrance.

CONCLUSIONS AND CLINICAL RELEVANCE CLP in the evaluated Alaskan Huskies involved mononeuropathy of the recurrent laryngeal nerves, without polyneuropathy. Most affected dogs had blue eyes, white facial markings, and oral mucosal tags or tissue bands. Given the apparent genetic component to CLP in this breed, we recommend that dogs with these features be prevented from breeding.

Abstract

OBJECTIVE

To evaluate effects of laparoscopic-assisted incisional gastropexy (LAIG) on gastric motility in dogs by use of a wireless motility device (WMD).

ANIMALS

10 healthy client-owned large or giant-breed dogs.

PROCEDURES

10 dogs owned by clients interested in prophylactic LAIG were enrolled. To determine effects of LAIG on gastrointestinal motility in dogs during the nonfed state, each dog was evaluated by use of a noninvasive WMD before and > 4 weeks after LAIG. All dogs underwent LAIG, with or without concurrent elective gonadectomy. Data obtained before and after LAIG were analyzed by use of proprietary software to determine the gastric emptying time, small bowel transit time, large bowel transit time, whole bowel transit time, and motility index.

RESULTS

No changes in variables were detected between measurements obtained before and after prophylactic LAIG.

CONCLUSIONS AND CLINICAL RELEVANCE

In this study, prophylactic LAIG did not have an effect on gastrointestinal motility. The WMD was tolerated well by all dogs and appeared to be a safe and effective method for evaluating gastrointestinal motility in this population of dogs.
