Behaviour Flashcards
What is the link between behvaiour and disease?
Behavioural changes occur due to alterations in an animal’s motivations this could be due to disease processes as well as emotional disorders
What are stressors and stress responses?
- Stressors are any physical or psychological stimuli that disrupt homeostasis
- The stress response refers to the physiological and behavioural changes which occur in response to a stressor
- These can be adaptive and appropriate to the stressor experienced or maladaptive and detrimental to the individual
How is the stress response mediated?
Mediated by the hypothalamic-pituitary adrenal (HPA) axis and the sympathetic-adreno-medullar (SAM) axis
What are the effects of cortisol and adrenaline?
- Increased blood pressure
- Increased blood glucose
- Immunosuppression
- Reduced blood flow to GI system
- Increased alertness
What is the sensory component of pain?
Transduction (tissue damaging stimuli detected by the nerve endings) > transmission > modulation > projection to the brain > perception in the cortex
What is the emotional component of pain?
Limbic system, leads to suffering
What is the cognitive component of pain?
Prefrontal cortex, learning, develop associations
What are the pain behaviours?
- Aggression – growling, lunging, snapping
- Hiding away
- Reluctance to move
- Lip licking, cowering
- Trembling/shaking
- Abnormal repetitive behaviours
- Altered gait
What are the pain classes?
Somatic
Visceral
Neuropathic
(Sympathetic)
How does acute pain affect behaviour?
- Acute pain is adaptive and helps protect an individual from damage
- Animals learn to avoid the stimulus in the future
What is nociplastic or maladaptive pain?
An abnormal pain state caused by ongoing inflammation and damage of tissues
What is central sensation of chronic pain?
Can develop central sensitisation leading to a high state of neuronal reactivity, with hyperalgesia and allodynia
What is neuropathic pain?
Sudden jumping or starting, followed by anxiety or aggressive behaviour towards those in the vicinity
How can GI health affect behaviour?
Pain, inflammation, malabsorption of nutrients and microflora dysbiosis
What are the behaviour changes that may occur as a result of GI disease?
- Inappetence
- Picky eating
- Struggling to settle
- Chewing of items
- Licking surfaces
- Burying food
- Anxiety
- If more motivated to chew items then may see resource guarding of those items
What are the behaviour signs to monitor due to GI disease?
Appetite at each meal
Plant/grass eating
Licking the environment
Licking themselves
Belching
Weight maintenance
Vomiting
Faecal scoring
What are the behavioural signs to monitor for urinary disorders?
- Grooming behaviour
- Location of urination
- Behaviour displayed whilst toileting e.g. posture adopted, movement, vocalisation
- Volume of urine passed
- Frequency of urination
- Owner reaction when animals urinate in undesired locations
What are the behavioural signs to monitor for musculoskeletal disease?
- Alterations in toileting – location, posture, incomplete elimination
- Reluctance to move from resting locations or into car etc
- Purposeful handling may be painful e.g. harness going on
- Overgrooming
- Altered gait/movement
- Changes in activity levels
- Noise sensitivity
- Gait
- Changes in way moves on stairs, on/off furniture etc
- Behaviour towards people
- Reaction to sudden noises
- Behaviour towards other dogs
What are the behavioural signs to monitor in dogs for reproductive disorders?
- Bitches less tolerant when in season
- False pregnancies
- Male-male aggression
- Male scent marking, humping
What are the behavioural signs to monitor in cats for reproductive disorders?
- Queens’ behaviour when in oestrus – ‘calling’
- Scent marking
- Fighting
- Larger territories
What are the behavioural signs of false pregnancies?
- Nesting, digging
- Carrying items like soft toys
- Hoarding items and mothering them
- Aggression around resources
- Anxiety
- Unsettled behaviour
How can the behavioural signs of false pregnancies be managed?
- Can be self-limiting
- Cabergoline - selective prolactin inhibitor
- Care not to neuter when in metoestrus, this can lead to a persistent false pregnancy
- Neuter in anoestrous – ideally 4 months after the end of oestrus
What are the behavioural signs to monitor of false pregnancies?
- Vulva – swelling and discharge
- Mammary glands
- Behaviour towards con-specifics
- Appetite
- Behaviour around resources
What are the behavioural changes of hyperthyroidism?
Hyperactivity, increased vocalisation, aggression, increased appetite
