Older Labs Susceptible to Laryngeal Paralysis
Older labs can be susceptible to laryngeal paralysis. An article written by California central valley veterinarian Jeff Kahler discusses a condition known as Laryngeal Paralysis which has a high incidence in older labs. This condition can be inherited or acquired. Some of the symptoms are coughing, change in bark tone, noisy breathing and others. The article is short and very informative. A recommended read especially if you own a lab or lab mix.
Pawsitive Paws recommends using a harness instead of a collar to protect your dogs neck region. Choke chains, pinch collars and other devices that can restrict breathing and otherwise damage the sensitive anatomy of the neck are highly discouraged.
