The American Animal Hospital Association’s 2015 Canine and Feline Behavior Management Guidelines ask veterinary teams to treat behavior as part of routine medical care, not as a side issue that gets attention only after a crisis. For pet owners, the useful parts are practical: when a behavior change deserves a veterinary visit, what humane management looks like, and where the guideline is cautious about medications and supplements. The ten points below walk through them in the order you are likely to need them.
What this guideline is, and how current it is
The guideline was developed by a task force convened by the American Animal Hospital Association (AAHA) and is presented as guidance rather than a rulebook. It combines cited evidence with practical experience and expert consensus. Its authors say some recommendations need further study, and they state that decisions for an individual animal should draw on the best available science together with the professional expertise of the veterinarian. You can read the scope and purpose on the AAHA 2015 guideline landing page.
The document is from 2015. AAHA’s online sections and toolkit material for it were posted in 2019. AAHA still lists the 2015 set in its current guideline index, alongside newer guideline resources. Read it as an established framework that is still in use, not as a newly issued document, and treat the specific dates and medication details below as the 2015 statements they are.
1. Behavior is part of ordinary veterinary care
AAHA’s stated goal is for veterinary teams to understand and meet the basic behavioral needs of dogs and cats. The guideline calls for building behavior management into everyday clinical practice. For an owner, this means behavior is a normal topic at a wellness or sick visit. You do not need a dramatic incident before raising it.

2. Ask about behavior routinely, and track change over time
The guideline calls for routine assessment of behavioral development and change, including the use of standardized assessment tools. The AAHA toolkit also emphasizes that how the client perceives the behavior matters, so your own account is part of the clinical picture. Your veterinarian will want to know what changed, when it started, and what you think is driving it.
A simple written log helps. Note the date, the situation, what the animal did, what happened just before, and any recent changes at home such as a new pet, a move, a schedule shift, or a visitor. Bring it to the appointment.
3. Use age as context, not as a diagnosis
AAHA notes that behavior-related relinquishment or euthanasia tends to occur most often during social maturity, at roughly ages 1 to 3 years. The guideline also recommends monitoring senior pets’ cognitive and physiological changes at least once a year, starting at the ages shown below. These are guidance ranges from AAHA’s 2019 toolkit summary of its 2015 guideline. They are not prevalence statistics, and an age in the table does not by itself indicate a problem.
Rank #2
| Animal and life stage | Guidance age range | What AAHA recommends |
|---|---|---|
| Dogs in social maturity | About 1–3 years | Context for behavior-related relinquishment or euthanasia, which AAHA says occurs most often in this period |
| Larger-breed dogs, middle age | 5–8 years | Annual monitoring of cognitive and physiological change, beginning in this range |
| Smaller-breed dogs, middle age | 8–10 years | Annual monitoring of cognitive and physiological change, beginning in this range |
| Cats, middle age | 10–12 years | Annual monitoring of cognitive and physiological change, beginning in this range |

4. Investigate meaningful changes instead of waiting them out
AAHA’s Table 5 lists concerning behaviors that call for veterinary assessment. The list includes:
- Fear or withdrawal from people or other animals
- Aggression
- Repetitive or ritualistic actions
- Changes in elimination
- New fears or phobias
- Distress when left alone
- Increased reactivity
- Major changes in activity or reactivity during rest or sleep
If your dog has suddenly become fearful, the guideline’s approach is to assess the change rather than label it as stubbornness or a phase. A sudden shift can have medical contributors, and the assessment described in the guideline includes looking for them. The full table is on the AAHA Table 5 page.
5. Keep the clinic low-stress for everyone
The guideline’s central practice goal is a low-fear, low-stress environment for patients, staff, and owners. Humane handling and the animal’s own response should guide decisions about restraint and medication during a visit. The guideline treats restraint as a procedure in its own right, not simply a convenient way to get another procedure done. If your pet is anxious in the waiting room or on the table, it is reasonable to ask the team how they handle that. The core competency section describes the practice-level approach.
6. Behavior care involves the whole team
AAHA describes a fully inclusive model. Team members should be able to read basic body language and recognize stress, fear, aggression, and withdrawal, and they should understand humane handling. A practice can name a behavior champion, and leadership is expected to provide support and staff education. Qualified trainers may contribute to a plan. Primary-care veterinarians are expected to refer to a veterinary behavior specialist when a case needs expertise the practice does not have.
7. Put safety and avoidance first
AAHA treats avoidance and safety as the foundation of behavioral treatment. In the guideline’s words, “Avoidance and safety are the cornerstones of behavioral treatment.” Preventing repeated exposure to the trigger protects a distressed animal while the team works out a treatment plan. In practice, that may mean managing the environment, such as separating a dog from a trigger or giving a cat a retreat space, before any training begins. Find the guideline text in the Changing behaviors section.

8. Use gradual, reward-based modification, and avoid flooding and aversive tools
The guideline describes counterconditioning as pairing a concerning stimulus with something the animal values, often alongside gradual desensitization kept below the threshold that provokes a reaction. The table below separates the approaches the guideline describes.
| Approach | How AAHA describes it | Status in the guideline |
|---|---|---|
| Counterconditioning with gradual desensitization | Pairs the trigger with something the animal values, at a level below the reaction threshold | The reward-based approach the guideline describes for changing behavior |
| Flooding | Exposes the animal to the trigger at a level that causes a fearful or aggressive response | Should be avoided |
| Aversive techniques | Include shock collars, choke or prong collars, alpha rolls, and beating | The guideline says that “None of those tools and methods should be used to either teach or alter behavior.” |
The quoted sentence about aversive techniques should be read in context: “those tools and methods” refers to the list above. The guideline also names toys and remote treat devices among nonaversive tools. A clicker is one plausible, optional aid for reward-based training, but the guideline does not specifically recommend clickers, and it does not say an owner needs one. Training does not replace a veterinary assessment or a treatment plan.

According to AAHA’s 2015 pharmacological section, medication should support safety, a suitable environment, and appropriate humane behavior modification. It is not a stand-alone fix. The guideline emphasizes risk assessment and monitoring, and it notes that side effects and drug interactions are possible. It also says some medication effects may take 5 to 8 weeks to appear, which means progress is judged over a longer timeframe than many owners expect. The pharmacological intervention page has the full context.

10. Be cautious with calming products and alternative treatments
The guideline reports that evidence for nutraceuticals and specialized diets was not sufficient to support evidence-based recommendations for their use. For pheromone products, it reports no expert consensus and no definitive evidence of efficacy. A product marketed for calming may be sold widely, but the guideline does not treat it as a proven treatment for fear or aggression. Bring any supplement, diet, or pheromone product you are considering to your veterinarian before you use it.
Questions to bring to your veterinarian
If a behavior change has you worried, these questions map directly onto the guideline’s approach:
- Could a medical problem be contributing, and what assessment would you recommend?
- Do you use a standardized behavior assessment, and can we start a log together?
- Which steps protect my pet’s safety at home while we work on the problem?
- Is reward-based modification appropriate here, and would a qualified trainer or a veterinary behavior specialist help?
- If medication is considered, how will we monitor risks, side effects, and progress over time?
The guideline’s underlying message is consistent across these points: assess early, keep the animal safe, change behavior gently, and monitor what happens.
