NORMAL ELIMINATION BEHAVIOR
 Puppies start to form substrate preferences between 7.5 & 8.5 weeks of age
 Location and surface preferences are common
 Females may need to eliminate more frequently than males
 By 6 months of ages, the average dog defecates 1/2 times a day, and urinates 3/4 times a day
 Urination postures sexually dimorphic by 4 months of age
 Functions in communication

Behavioral History
 Duration of problem ® prognosis
 Frequency
 Areas soiled ® type of substrate
 Timing of the episodes ® association with external stimuli
 Presence or absence of owner ® S.A. 
 Underlying medical conditions
 Changes in household environment, in schedule, exercise routine
 Corrections tried and responses
 Changes in the pattern of the problem
 Substrates or location preferences
 Urine deposited in numerous locations in small amounts
 If multi-pet household, which pet is the problem
 Response to confinement
Basic Rules For Housetraining Puppies
 Puppies usually eliminate after physical activities
 Take outside frequently
 Allow puppy to play after elimination
 Reward for eliminating at the appropriate location
 Regular feeding and exercising schedules ® regular elimination 
 Take the dog to same areas, Supervision / Confinement
 Recognize pre-elimination signs, appropriately timed correction
 Clean affected areas with odor eliminator
 Don't punish the puppy unless you caught him in the act, avoid physical punishment
Basic Rules For Housetraining Older Dogs
 House-train the dog as if it were a puppy
 Take the dog out after eating, physical activity and waking up
 Supervise closely in the home, confine when not supervised
 Keep rewards only for eliminating at the appropriate location
 Mildly punish the dog if you caught him in the act
 Stop feeding the dog in the late afternoon. Do not allow the dog access to water after 7:00 p.m.
SUBMISSIVE URINATION
Puppy or submissive older dog urinates and shows the submissive behavior when approached, punished, picked up, greeted, etc.
 Genetic predisposition ® Suspected in cases where no obvious environmental cause
 Early experience deficit ® Associated with fear of certain types of human beings because of lack of experience with them early in life
 History of punishment ® problem can result from the owner's application of punishment measures
 Unintentional owner eliciting/ fostering ® can be response to dominant / aggressive owner behavior
 Unintentional owner reinforcement ® owner stops doing something to the dog or comforts / reassures in response to urination
Submissive Signaling
 Flattening of ears
 Avoidance of eye contact
 Lowering of head and neck
 Sitting /Cowering/ Crouching
 Tucking the tail
 Rolling onto the back
 Submissive "grin"
Stimuli That Trigger Urination
 Person approaches
 Reaches toward or over dog's head
 Patting on the head
 Deep or loud voice
 Direct eye contact
 Scolding or physical punishment
Treatment
 Neither punish nor reward
 Identify specific eliciting stimuli and avoid them
 Obedience training must focus on positive reinforcement
 Interact with pet in less threatening manner:
 Kneel down, speak softly, pat under chest rather than over head, avoid eye contact, ignore the greeting, allow dog to approach first
 Desensitization and counterconditioning
 Start with an empty bladder, identify a gradient of eliciting stimuli, present lowest level stimulus first, non- threatening presentation of stimuli, gradually increase intensity of stimuli, teach competing response, such as sitting for food reward
EXCITEMENT URINATION
 Dog urinates while standing or walking when highly excited during greeting, playing, etc.
 Submissive signals are absent 
Possible Causal Factors
 Genetic predisposition ® possible explanation of why some dogs are incontinent in excitement-eliciting situations
 Inadequate care/maintenance conditions ® excitement greater after period of social isolation / lack of activity
 Unintentional owner fostering ® owner behavior during greeting / playing may increase dog's excitement
 Physiological factors ® low bladder / bladder sphincter tone
Treatment
 Avoid stimuli that elicit the behavior
 Ignore dog until excitement subsides
 Provide frequent opportunities to eliminate outside
 Increase exercise
 DS / CC
 Punishment will be unsuccessful
 Medications to increase sphincter tone
 Reinforce calm behavior
MARKING
 Male raises hind leg and deposits small amounts of urine on vertical surfaces or corners of objects in the home
 Age of onset is variable; can be as early as 3 months
 May reflect relative social rank: dominant animals more likely to cover a subordinate's urine
Possible Causal Factors
 Genetic predisposition as possible contributing factor in some cases
 Urine-elicited marking ® old marks often investigated and marked over
 Social eliciting stimuli ® visiting dog in home, estrous bitch nearby, other dog marking in home
 Hormone factors: problem much more common in males, castration often helpful
 Associated with specific territorial or anxiety- eliciting stimuli
Treatment
 Neutering or spaying: castration may eliminate male marking behavior in approximately 50%
 Therapy based on detailed behavioral history
 Prevent exposure to stimuli that elicit marking: limit exposure to outside dogs
 Avoid situations that make the pet anxious
 Remote punishment
 Confinement when not supervised
 Clean marked areas, urine deposits elicit remarking
 Anti-anxiety medications
 Hormones
SEPARATION ANXIETY
 Dog never eliminates in the house when the individual is present and awake; may or may not have a problem when the owner is asleep
 Symptoms include excessive vocalization, house soiling and destructive behavior (especially around doors or windows)
 Occurs only when owners, or a particular individual, are away or visually separated from dog
 Dog often become anxious while owner prepares for departure
 Treatment of underlying problem -separation anxiety
MISCELLANEOUS CAUSES OF ELIMINATION PROBLEMS
 Changing feeding schedule
 Schedule changes resulting in insufficient access
 Fear of outside: traffic, noises, other dogs
 Elimination associated with fear
 Attention- seeking behavior
 Geriatric cognitive dysfunction
