Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

◐Partially SupportedAG1 is an all-in-one supplement providing vitamins, minerals, probiotics, adaptogens, and digestive enzymes.

◐Partially SupportedSecure attachment bonds in dogs, formed by responsive caregivers, enable better self-regulation and quicker nervous system calming after stressors.

✓Well SupportedThe human brain devotes a significant amount of its capacity to vision, indicating its evolutionary importance.

◐Partially SupportedThe breeding out of pain receptors in English bulldogs is correlated with a fibronectin mutation, contributing to their droopy appearance and short snout for gripping.

◐Partially SupportedHumans uniquely learn from knowledge accumulated over thousands of years, allowing them to stand on the shoulders of giants.

◐Partially SupportedTo feel calm and safe, animals should be placed in a state of low arousal and pleasantness.

◐Partially SupportedKittens handled for less than 15 minutes per day between two and eight weeks of age will not be fearful of humans but will approach and then walk away.

◐Partially SupportedLiving with dogs allows for observation of the entire animal, improving interpretation of their facial expressions which differ from human emotional states.

◐Partially SupportedPFAS (forever chemicals) are found in 80% of non-stick pans, utensils, appliances, and other kitchen products.

◐Partially SupportedDogs form attachment bonds with humans, which can be securely or insecurely attached, rather than imprinting on them.

◐Partially SupportedFeeding multiple cats in separate locations reduces arousal due to their solitary hunting nature.

◐Partially SupportedNeutering, particularly in males and depending on age, can increase fear, reactivity, aggressive behavior, and noise sensitivity.

◐Partially SupportedCaptive feeding of horses often promotes rapid consumption compared to natural foraging, potentially leading to problem behaviors.

◐Partially SupportedHounds are bred to be excellent sniffers, and all dog breeds likely enjoy sniffing.

◐Partially SupportedLivestock guardian dogs tend to retain the sniffing aspect of the predatory sequence but show less of other components.

◐Partially SupportedA cat may urinate outside the litter box if it associates the box with painful experiences.

◐Partially SupportedIntroducing unfamiliar animals requires a gradual process involving scent exchange, auditory cues, visual contact, and finally tactile interaction to reduce the risk of aggression.

◐Partially SupportedHumans can learn to read dog signals through passive exposure and association.

◐Partially SupportedScatter feeding or using snuffle mats can make dogs work for their food, which is more engaging than a bowl for dogs that inhale food.

◐Partially SupportedTeaching dogs to stay in the initial parts of the predatory sequence can be a strategy for dogs that chase wildlife.

◐Partially SupportedSome veterinarians discourage neutering animals unless medically necessary, citing health benefits to keeping hormones intact.

◐Partially SupportedDogs may prefer slow, deliberate strokes over quick patting.

◐Partially SupportedDogs may need cognitive work and mental challenges to prevent boredom, especially on days with poor weather preventing outdoor activity.

◐Partially SupportedSecurely attached individuals can self-regulate their nervous systems more easily after a stressor compared to insecurely attached individuals.

◐Partially SupportedDogs generally prefer tactile stimulation on their neck or upper chest over having a hand placed on top of their head.

◐Partially SupportedEngaging animals and providing stimulation helps prevent boredom and depression.

◐Partially SupportedTerriers were intentionally bred over centuries to be highly effective killers of small rodents.

◐Partially SupportedScientific knowledge is dynamic and assumptions made with conviction may be proven false in the future.

◐Partially SupportedReading a dog's body language is often more reliable than interpreting their facial expressions.

◐Partially SupportedCalm humans can transmit subtle cues that help relax animals, related to polyvagal theory and co-regulation.

◐Partially SupportedAttachment bonds between caregivers and offspring develop differently based on the caregiver's responsiveness to the young one's needs.

◐Partially SupportedDiscuss the optimal procedure for a dog (neutering, sterilization, or other) with a veterinarian, considering breed, gender, and age.

◐Partially SupportedTo distinguish play from aggression in dogs, one can look for meta-signals (M), activity shifts (A), roll reversals (R), and self-handicapping (S).

◐Partially SupportedNeutering can increase the risk of certain cancers and physical problems while decreasing the risk of others.

◐Partially SupportedCats covering their waste in the wild may reduce the risk of infection.

◐Partially SupportedInbreeding avoidance prevents many animal species from mating with individuals too genetically similar to themselves to avoid inbreeding depression.

◐Partially SupportedA sense of safety is a high priority for animals because a lack of safety can lead to death.

◐Partially SupportedCats do not typically eliminate near where they eat, so their litter box should not be placed next to their food.

◐Partially SupportedMany horses find patting to be an aversive behavior, though they may enjoy wither scratching.

✕Not SupportedThe common advice that a dog should walk beside or behind its owner is likely based on owner training and learned consequences, not inherent dominance.

✕Not SupportedFeeding a dog after its owner is based on establishing a relationship and learning expectations, not dominance.

◐Partially SupportedTactile stimulation can help animals move from unpleasant emotional states to a relaxed, safe, and socially engaged state.

◐Partially SupportedA consent test involving initiating and withdrawing physical contact can determine if an animal tolerates or enjoys the interaction.

◐Partially SupportedCapuchin monkeys reacted negatively to unequal distribution of rewards (cucumber vs. grape).

◐Partially SupportedTexting can be a tool for self-regulation or a way to avoid dealing with stress and uncertainty.

✕Not SupportedSeparating puppies from their mother at 8 weeks is too early from an ethological perspective and shows detrimental effects.

◐Partially SupportedGroup selection plays a role in species evolution, though individual selection is stronger.

◐Partially SupportedProcedures like vasectomies or tubal ligation can prevent reproduction without removing reproductive organs, allowing for continued production of hormones.

◐Partially SupportedDog breeds were selectively bred for specific aspects of the wolf predatory sequence.

◐Partially SupportedThe behavior of dogs kicking dirt in the direction of their feces after elimination is likely a way of spreading scent, not covering waste.

◐Partially SupportedIn cows, a 'controller' animal may initiate a change in activity that the rest of the herd then synchronizes with.

◐Partially SupportedDogs' facial expressions may not directly correspond to human emotional states due to different muscle usage.
