To compare how often owners identified concerns about their pets’ behavior during routine examinations in 2 test conditions (voluntarily or when completing a questionnaire), and to test the efficacy of a simple behavior screening questionnaire to be used by practicing veterinarians.


Privately owned dogs and cats presenting for routine examinations to 1 of 2 primary care clinics.


The study was conducted in 2 sequential phases. In Phase 1, veterinary staff recorded whether pet owners or veterinarians inquired about behavior during routine examinations. In Phase 2, a different set of pet owners completed a short behavioral screening questionnaire as they waited for the veterinarian. We compared the 2 phases for how often behavior concerns were identified, the types of concerns, the pets’ ages, and the owners’ levels of satisfaction and desire for help.


Dog and cat owners were more likely to identify behavior concerns when prompted than they were to volunteer this information, especially for older patients in which behavior changes may be the first sign of disease. Most owners were satisfied with their pets’ behavior, though owners were more likely to be unsatisfied with certain identified concerns. Owners who were dissatisfied were much more likely to want help.


A behavior screening questionnaire enhances detection of behavior problems that may have medical implications and impact the security of the pet in its home. A behavior screening questionnaire can elevate standard of care by enabling veterinarians to quickly assess behavior during every examination.

OBJECTIVE To compare the doses of propofol required to induce general anesthesia in dogs premedicated with acepromazine maleate or trazodone hydrochloride and compare the effects of these premedicants on cardiovascular variables in dogs anesthetized for orthopedic surgery.

DESIGN Prospective, randomized study.

ANIMALS 30 systemically healthy client-owned dogs.

PROCEDURES 15 dogs received acepromazine (0.01 to 0.03 mg/kg [0.005 to 0.014 mg/lb], IM) 30 minutes before anesthetic induction and 15 received trazodone (5 mg/kg [2.27 mg/lb] for patients > 10 kg or 7 mg/kg [3.18 mg/lb] for patients ≤ 10 kg, PO) 2 hours before induction. Both groups received morphine sulfate (1 mg/kg [0.45 mg/lb], IM) 30 minutes before induction. Anesthesia was induced with propofol (4 to 6 mg/kg [1.82 to 2.73 mg/lb], IV, to effect) and maintained with isoflurane or sevoflurane in oxygen. Bupivacaine (0.5 mg/kg [0.227 mg/lb]) and morphine (0.1 mg/kg [0.045 mg/lb]) were administered epidurally. Dogs underwent tibial plateau leveling osteotomy (n = 22) or tibial tuberosity advancement (8) and were monitored throughout anesthesia. Propofol induction doses and cardiovascular variables (heart rate and systemic, mean, and diastolic arterial blood pressures) were compared between groups.

RESULTS The mean dose of propofol required for anesthetic induction and all cardiovascular variables evaluated did not differ between groups. Intraoperative hypotension developed in 6 and 5 dogs of the acepromazine and trazodone groups, respectively; bradycardia requiring intervention developed in 3 dogs/group. One dog that received trazodone had priapism 24 hours later and was treated successfully. No other adverse effects were reported.

CONCLUSIONS AND CLINICAL RELEVANCE At the described dosages, cardiovascular effects of trazodone were similar to those of acepromazine in healthy dogs undergoing anesthesia for orthopedic surgery.

Objective—To evaluate associations between retention of dogs in their adoptive homes and attendance at puppy socialization classes and other factors.

Design—Epidemiologic survey.

Animals—248 adult dogs that were adopted as puppies from a humane society.

Procedure—Owners completed questionnaires regarding demographics, retention of the dogs in the homes, and the dogs' early learning events.

Results—Higher retention in the homes was reported for dogs that participated in humane society puppy socialization classes, were female, wore headcollars as puppies, were handled frequently as puppies, were more responsive to commands, slept on or near the owner's bed, or lived in homes without young children.

Conclusions and Clinical Relevance—Results suggest several practices that veterinarians may recommend to enhance the likelihood that puppies will remain in their first homes, such as enrolling 7- to 12-week-old puppies in early learning and socialization classes. The lower rate of retention of dogs in homes with children emphasizes the importance of helping owners develop realistic expectations, knowledge, and effective tools to manage interactions between their children and dogs.
