This why capnography is a must-have piece of equipment.

Tech Tip Tuesday: Capnography Case Scenario

You’re monitoring a dog under anesthesia for a routine spay.

Everything has been stable until you notice this:

• ETCO₂ was 38 mmHg… now trending down to 25 mmHg
• The waveform is getting smaller
• Your patient’s SpO₂ still reads normal

ETCO2=35−45 mmHg

What’s your next move?

Before you assume hyperventilation...pause.

Low ETCO₂ doesn’t always mean the patient is “breathing too well.”

Think through your differentials:

Could this be:
• A disconnect in the circuit?
• A leak in your ET tube cuff?
• Decreased cardiac output?
• Early sign of impending arrest?

Now check your patient:
You quickly assess:

Chest movement → present
Reservoir bag → feels normal
Pulse quality → weak

Now your concern shifts.

ETCO2 not only measures ventilation issues, this could be circulatory compromise.

Why this matters:
Capnography often changes before anything else. A dropping ETCO₂ with a weakening pulse should immediately make you think about perfusion, not just breathing.

Technician Insight:
Capnography is one of the earliest indicators of decreased cardiac output.

If you only look at the number, you’ll miss it.
If you interpret the trend with your physical assessment of the patient, you’ll catch it early.

The assertion that force-free training causes dogs with behavior problems to be euthanized assumes a false choice: either use aversive methods or dogs die.

That framing ignores both the scientific literature on behavior change and the many reasons dogs are surrendered or euthanized.
Blaming force-free trainers for euthanasia oversimplifies canine behavior problems and ignores what modern behavioral science actually shows.

First, euthanasia decisions are usually multifactorial. Dogs are euthanized because of severe behavioral pathology, lack of access to qualified help, unrealistic owner expectations, housing instability, financial limitations, medical issues, poor breeding, inadequate early socialization, chronic stress, or safety concerns. To place responsibility primarily on trainers who avoid aversive methods is not based on evidence.

Second, aversive methods do not reliably “fix” aggression or serious behavior problems. Punishment can suppress outward behavior temporarily without addressing the underlying emotional state driving the behavior. A dog may stop growling, barking, or lunging while fear, anxiety, frustration, or conflict remain unchanged—or worsen.

This creates the risk of behavioral suppression rather than genuine rehabilitation. Board-certified veterinary behaviorists and Certified Applied Animal Behaviorists, as well as many highly qualified professional trainers understand this and warn that punishment can increase fear, stress, and defensive aggression in dogs.

Third, force-free training is not synonymous with permissiveness. Skilled positive reinforcement trainers use structure, reinforcement of alternative behaviors, environmental management, systematic desensitization, counterconditioning, a variety of non-pharmacological adjunctive therapies, and carefully constructed behavior modification plans to modify behavior. Saying “force-free” means “no boundaries” is a misunderstanding of the methodology.

Fourth, humane training methods improve owner compliance and preserve the human-animal relationship. Most owners are unwilling or emotionally unable to use harsh corrections consistently – which is a good thing!

But inconsistent and improper use of punishment – which describes the way 99.9999 % of people administer punishment can not only result in worsened behavior, but also reinforcement in all the wrong places – including reinforcement of punishing behavior on the part of the owner who perceives quick results.

Most, if not all dogs deteriorate behaviorally under confrontation-based handling. Force-free approaches often keep owners engaged in the process over the long term, which may increase the likelihood their dog remains in the home.

This also provides the opportunity for the training instructor or behavior consultant to educate the owner on behavior, better communication, and science-based behavior modification.

Fifth, the claim selectively ignores fallout from aversive methods themselves. Many dogs are surrendered or euthanized after bite incidents that occurred in contexts involving intimidation, flooding, leash corrections, alpha-rolls, shock collars, or escalating conflict between dogs and their human family.

If euthanasia is being used as the metric, then trainers using aversive methods must also account for cases where punishment contributed to worsening fear, aggression, or damaged relationships.

Finally, the debate should not be framed as morality versus reality. Ethical force-free trainers acknowledge that not every dog can be safely rehabilitated, and that management, medication, environmental change, or even behavioral euthanasia may sometimes be necessary in extreme cases.

The question is not whether a dog could be saved with harsher methods, but can the dog be saved with the best we have to offer.

🐕 A new study from the RVC has revealed that three popular designer Poodle-crossbreeds (often generically called Doodles), Cockapoos, Labradoodles and Cavapoos, often display higher levels of undesirable behaviour than their purebred parent breeds. As the first UK study of its kind, these findings challenge widespread public perceptions that these Doodle breed dogs are easier to train or especially suited to family homes with children compared to purebred dogs. The results also provide vital information which can assist prospective owners deciding which type of dog to welcome into their family.

A recent study in the Journal of Feline Medicine and Surgery focusing on UK owners caring for cats with chronic kidney disease (CKD) found that many of them experienced significant anxiety and emotional burden while managing their cat’s condition 👉 https://journals.sagepub.com/doi/full/10.1177/1098612X251314769

For veterinary teams, this highlights an opportunity for empathetic communication, education, and ongoing support to help reduce the caregiver burden and improve compliance with treatment plans.

Practical takeaways 👇

🐱 Ask caregivers how they’re coping
🐱 Provide clear guidance on monitoring and treatment
🐱 Reinforce that the veterinary team is a partner in the care of their cat

By recognising the caregiver side of CKD, we can strengthen the veterinary professional and caregiver partnership and support better outcomes for cats.

Take a moment today to reflect - how does your clinic support CKD caregivers?
