Prevalence and characteristics of foal rejection in Arabian mares.
Separate surveys of Thoroughbred, Paint, and Arabian mare owners revealed a higher than expected rate of foal rejection in Arabian mares. A behavioural history form was submitted by owners of foal rejecting and nonrejecting Arabian mares, and maternal behaviour and management practices compared. Four generation pedigrees of rejecting and nonrejecting Arabian mares were also examined. Foal rejecting mares were more likely to avoid, threaten, squeal at, chase, bite, and kick their foals post partum than nonrejecting mares. Nonrejecting mares were more likely to lick, nicker and defend their foals post partum than rejecting mares. No statistically significant relationship was found between foal rejection and the type of breeding method (natural vs. artificial insemination), the presence of people at birth, the presence of nearby horses at birth, or assistance of the first nursing bout. The presence at least once of 1 of 2 related sires was statistically higher in the pedigrees of rejecting vs. nonrejecting mares. Inherited and learned or environmental factors are likely to affect the expression of foal rejection behaviour.

Social dynamics and behavior problems in multiple-dog households.
Certain behavior problems can be aggravated by the presence of conspecifics. Behavior problems that can occur in multiple-dog households as a result of social facilitation are discussed, along with behavior modification and pharmacologic treatments necessary to manage the problem.

Assessment and treatment of excessive barking in the domestic dog.
Barking is a normal and common method of communication in the domestic dog, but it can become a problem behavior in specific circumstances. Excessive barking can be a mild annoyance or a severe problem, particularly if the owner is under pressure from other people to stop the dog's behavior. Preventive measures could reduce the likelihood of the behavior becoming problematic. Correctly assessing the motivation behind a dog's excessive barking once it becomes a problem is crucial to the implementation of a successful treatment regimen. Veterinarians should be prepared to give practical advice to clients in both instances, because the recommendations could improve the chance of the dog staying in the household.
