A quick note before we start: dog behavior is a genuinely deep field, and this article is meant as a general, everyday guide, the kind of thing that’s useful on a normal walk or at home. If your dog is showing aggression, severe fear, or other behavior that concerns you, that’s a job for a certified professional dog trainer or veterinary behaviorist, not a blog post. This is a starting point, not a substitute for professional help.

Dogs communicate constantly. Through their ears, tail, posture, and eyes, they’re telling you exactly how they feel, if you know what to look for.

The tail

A wagging tail doesn’t always mean “happy,” and the details matter more than most people realize. According to Renee Rhoades, an animal behaviorist at R+Dogs, dogs actually show at least five distinct tail positions: a fast, high wag usually signals anticipation (like waiting for a treat), a high, sweeping wag often means genuine excitement, a stiff, still, upright tail can mean your dog feels threatened and is assessing a situation, a loose, low, hanging tail usually means your dog is relaxed, and a tucked tail signals fear or anxiety.

The ears

Relaxed, neutral ears mean a relaxed dog. Ears pinned back can mean fear or submission. Ears fully forward and alert often mean your dog has spotted something interesting, or is on guard.

The whole body

A play bow (front end down, rear end up) is one of the clearest and most delightful signals dogs give, an open invitation to play. A stiff, still body with a fixed stare is worth paying attention to, since it can precede a defensive reaction. A relaxed, loose-bodied dog with soft eyes is a genuinely content dog.

The eyes

Soft, relaxed eyes signal comfort. Wide eyes showing the whites (sometimes called “whale eye”) usually signal stress or discomfort. A hard, direct stare can be a warning sign, especially paired with a stiff body.

What the experts say

Reading body language isn’t guesswork, it’s a real skill that professionals study closely. Certified dog behavior consultant Michelle Mullins puts it simply: with dogs, “what they’re feeling and what their body is saying is exactly the same thing.” Unlike humans, who can mask emotions, dogs’ bodies are a fairly direct readout of their internal state.

Dr. Melissa Bain, a veterinary behaviorist at UC Davis School of Veterinary Medicine, notes that visual communication is especially important for dogs, since it can shift instantly based on how an interaction unfolds. That’s why a single signal rarely tells the whole story. Context, and the combination of signals together, matters more than any one cue alone.

Why this matters

Learning to read these signals helps you understand your dog’s world. It can help you know when they’re truly enjoying a greeting versus tolerating it, when they need space, and when they’re simply, happily, being a dog. If you ever notice a pattern of fear or aggression you can’t make sense of, that’s the moment to bring in a certified trainer or veterinary behaviorist. But for everyday walks and everyday life, the better you get at reading these basics, the stronger the conversation between you and your dog gets, even without a single word.

If you’ve ever wondered whether your dog is getting too much exercise, too little, or exactly the right amount, you’re not alone. It’s one of the most common questions dog owners have, and the honest answer is: it depends. A lot.

According to Danielle Rakestraw, a certified trainer and shelter engagement specialist at Best Friends Animal Society, there’s no single formula. The right amount and type of exercise depends on your dog’s individual breed, age, size, personality, and overall health, not just a chart.

Why exercise matters: body and mind

Exercise isn’t just about burning energy. It affects your dog on two levels, physical and mental, and both matter.

Physical benefits include maintaining a healthy weight, supporting joint and muscle health, improving cardiovascular fitness, and better sleep quality.

Mental benefits are just as real, though less obvious: reduced boredom-driven destructive behavior, lower anxiety and stress, and genuine mental stimulation. Dr. Susan Nelson, a clinical professor at Kansas State University’s College of Veterinary Medicine, notes that dogs need an outlet for their energy or they can develop destructive behavior, and that a dog who gets adequate exercise is simply a happier, more content dog to live with. That last point matters more for some breeds than others. Working and herding breeds, in particular, were bred to think for a living, not just move. A tired body isn’t the same as a satisfied mind, and a dog who’s physically worn out but mentally under-stimulated can still be restless, anxious, or destructive.

By age

Puppies are bursting with energy but their joints and growth plates are still developing, so short, frequent bursts of play beat one long walk. A good rule of thumb is about five minutes of structured exercise per month of age, twice a day, until they’re fully grown.

Adult dogs, generally one to seven years old, need the most consistent daily exercise: most do best with 30 to 60 minutes of real activity a day, not just a stroll around the block.

Senior dogs still need to move. Regular, gentler exercise keeps joints mobile and muscles strong. Shorter, more frequent walks usually work better than one long outing.

By breed type, with real examples

High-energy breeds (Border Collies, Australian Shepherds, most working and herding breeds) genuinely need real exercise, often 60-90 minutes a day, and thrive on mentally demanding activity, not just physical. Good options: running or jogging alongside you, fetch, agility courses, herding-style games (even in a backyard), target training, and advanced obedience or trick training. These breeds especially benefit from “job-like” activity that gives their brain something to solve.

Moderate-energy breeds (many spaniels, retrievers, terriers) do well with 30-60 minutes of varied activity. Good options: daily walks combined with fetch, swimming, moderate hiking, and scent-based games like hiding treats around the yard.

Lower-energy breeds (Bulldogs, Basset Hounds, many toy breeds) still need daily movement, just shorter and gentler. Good options: short leisurely walks, gentle indoor play sessions, and puzzle feeders for mental engagement without physical strain. Flat-faced breeds tend to have more heat intolerance than longer-nosed breeds, so they should avoid strenuous exercise, particularly in heat, since they overheat more easily doing the same activity as a Collie or Lab.

The real test

Numbers are a starting point, not a rulebook. A dog getting enough exercise, physically and mentally, is generally calm at home, sleeps well, maintains a healthy weight, and isn’t destructive out of boredom. If your dog seems restless, gaining weight, or acting out, more movement (and more mental engagement) is often the simplest fix.

Walk down the dog food aisle and you’ll see “grain-free,” “holistic,” “human-grade,” and a dozen other labels competing for attention. Some of it matters. A lot of it is marketing. We sat down with Dr. Rollins, a veterinary nutritionist, on the We Are The Cure Podcast to separate the two.

What actually matters on the label

Look for a named protein source (chicken, beef, salmon) as the first ingredient, not a vague “meat by-product.” Check for a statement that the food is formulated to meet AAFCO nutrient profiles for your dog’s life stage, the baseline guarantee that a food is nutritionally complete. And match the food to life stage: puppies, adults, and seniors have meaningfully different needs, particularly around protein and calorie density.

The grain-free lesson: a cautionary tale worth knowing

A few years ago, grain-free diets dominated the market, often marketed as healthier or even cancer-protective. According to Dr. Rollins, that push was driven almost entirely by marketing, not medical evidence. The unintended consequence: many manufacturers simply swapped grains for high levels of legumes like peas and lentils. In dogs eating diets marginal in protein and taurine, with a lot of that protein coming from legumes, researchers began noticing a possible association with dilated cardiomyopathy, a serious heart condition. As Dr. Rollins put it, the relationship is “multifactorial” and “very complicated,” likely involving both genetics and diet, and still not fully understood. The bigger lesson: when a pet food company markets what a food doesn’t contain, it’s worth asking whether there was ever a real reason to avoid it in the first place.

If you want to cook at home, do it the safe way

Homemade diets can absolutely work, and veterinary nutritionists build them for clients regularly, often to manage specific medical conditions. But there’s an important distinction: a professionally formulated homemade diet is complete and balanced, with the right vitamins and minerals added in. An ad hoc homemade diet (say, sweet potatoes and lamb) usually isn’t, and can quietly cause nutrient deficiencies over time.

If you want to explore home cooking, Dr. Rollins recommends starting at balanceit.com, a resource built by a board-certified veterinary nutritionist that provides complete, balanced recipes along with the supplements needed to round them out. For anything more customized, especially for a dog managing a medical condition, a consultation with a veterinary nutritionist (often available via telemedicine nationwide, with a referral from your regular vet) is the more reliable path.

A few other things worth knowing

Exotic proteins aren’t automatically the answer to allergies. Duck, venison, and elk diets have become popular for dogs with suspected food allergies, but Dr. Rollins flags a real issue: unless a manufacturer thoroughly cleans equipment between production runs, an “elk” diet may still carry trace contamination from a chicken diet made on the same line, similar to how peanut cross-contamination works in human food facilities. True food allergy diagnosis typically requires an elimination diet or a hydrolyzed protein diet under veterinary guidance, not just switching to a novel protein off the shelf.

Salmon is great, but not as a sole protein source. It’s an excellent source of omega-3 fatty acids, but a diet built entirely around salmon can push vitamin D too high, since dogs are more sensitive to excess vitamin D than humans. It’s usually paired with a second protein source for balance.

The 10% rule for treats and table food. If you want to share human food or treats, keep it under 10% of your dog’s total daily calories. Go beyond that regularly, and you risk throwing off their calcium and vitamin balance, even if the extra food seems harmless.

The bottom line

Good nutrition doesn’t have to mean chasing the latest trend. A named protein source, AAFCO life-stage certification, and a healthy weight and coat are strong everyday signals you’re on the right track. For anything more specific, whether that’s a medical condition, a suspected allergy, or questions about your dog’s diet during cancer treatment, a conversation with your vet or a veterinary nutritionist is worth far more than another label claim.
