Puppies have their behavior problems, and older dogs have theirs. For
older dogs, in many cases it is not that they do not understand the 'rules,'
but that they may, for many reasons, be unable to follow them.
Separation anxiety is one of the most common behavior problems seen
in older dogs. A dog who has separation anxiety will become very anxious
when he senses his owner is about to leave. When the owner does leave,
the dog often becomes destructive, barks or howls, may urinate or defecate,
and may salivate profusely. A dog with separation anxiety will often
be overly exhuberant when his owner returns.
Older dogs may have a decreased ability to cope with changes in routine.
Vision or hearing loss may make them more anxious, overall, but especially
when they are separated from the owner. Neurologic changes may also limit
an older dog's ability to adjust to change.
Some of the main considerations in treating separation anxiety are:
- Do not make a big deal about leaving or coming home -
that simply reinforces the behavior.
- Teach your dog to relax. If your dog can learn to relax
in a 'stay' for extended periods while you are there, he will be more
likely to learn how to relax while you are gone.
- Change your departure cues. Many dogs know as soon as
the alarm goes off, that it is a work day and you are going to leave.
They start getting anxious as soon as they hear the alarm. We need
to change our routine so the dog does not know we will be leaving.
For instance, pick up the car keys and then go sit on the couch; on
a Saturday, get up and dress like you are going to work, but stay home.
- Start with very short departures. Determine how long
you can leave your dog before he gets anxious. It may be only 10 seconds,
so start there. Leave for 5 seconds, return, and if the dog has remained
calm, reward him. Gradually increase the time you are gone, always
returning before the dog becomes anxious, and rewarding him for staying
calm. This may take weeks to months, so patience is the key.
your departure with something good. As you leave, give your dog a hollow
toy such as a 'Kong' filled with a wonderful treat. This may take his
mind off of you leaving. Anxiety tends to feed on itself, so if we
can prevent the anxiety from occurring when you leave, the dog may
remain calm after you leave. Make sure your dog's environment is comfortable:
the right temperature, a soft bed, sunlight, 'easy-listening' music.
Some dogs will be more relaxed if they can see the outside world, others
may become more anxious. Similarly, some older dogs are more anxious
when left outdoors, and do much better when they can stay in the house.
Determine what is best for your dog.
- Break up the dog's day. If you are gone for extended
periods during the day, you may want to think about having someone
come in during the day to let your dog out and give him some exercise.
Older dogs, especially, may need to go outside more often to urinate
and defecate. Giving them this opportunity may decrease their anxiety.
- Crate your dog. Many dogs feel safe in a crate, and being
in a crate will help reduce their destructiveness. This will make it
safer for them and your house.
a team approach. Anti-anxiety medications such as Clomicalm are
often needed to break the cycle of separation anxiety. Medication alone,
however, will not solve the problem. Work with your veterinarian and
an animal behaviorist to develop a plan that will work best for you
and your dog.
Older dogs may become
aggressive for several reasons. Aggression may be the result of a medical
problem such as one causing pain (arthritis or dental
disease), vision or hearing loss, which results in the dog being
easily startled, lack of mobility so the dog can not remove himself from
the irritating stimulus (e.g.; an obnoxious puppy), or diseases having
direct effects on the nervous system, such as cognitive dysfunction (see
below). Stresses such as moving, a new family member, or a new pet may
make an older dog more irritable and more likely to be aggressive. In
a multi-dog household, an older dog who was the 'dominant' dog in the
past, may find his authority being challenged by younger dogs in the
determining what factors may be contributing to the aggression, we may
be able to eliminate or reduce those factors. Treating medical conditions
which contribute to the aggression is paramount. Watch the dog for signs
of stress (increased panting), and remove the dog from the stressful
situation which could cause aggression. Using a 'halti'
headcollar and leash may provide more control over an older dog,
especially one who has decreased hearing or vision. In some cases, a
basket muzzle may be needed to assure the safety of human and non-human
family members. DO NOT LEAVE A MUZZLED DOG UNATTENDED. Medications can
be helpful in reducing aggression that may be due to fear and anxiety.
As with separation anxiety discussed above, medication alone will not
solve the problem. Work with your veterinarian and an animal behaviorist
to develop a plan that will work best for you and your dog.
Some older dogs who
have been housetrained for years, may start having 'accidents.' As
with other behavior problems in older dogs, there may
be multiple causes for this change in behavior. Medical conditions which
result in an increased frequency of urination or defecation may be the
underlying cause for this behavior problem. These conditions include:
bowel disease, diabetes
mellitus, bladder stones or
infections, inflammation of the
prostate, Cushing's disease,
and kidney or liver disease.
Medical conditions which cause pain or make it difficult for the dog
to go outside to eliminate can also contribute to the problem. These
conditions include arthritis, anal
sac disease, loss of vision, and some forms of colitis. Treatment
of these medical conditions may help to resolve this behavioral problem.
Some medical conditions can result in a loss of control over bladder
and bowel function and include hormone
responsive incontinence, prostatic disease, and cognitive dysfunction.
As discussed earlier, separation anxiety may result in defecating and
urinating when the dog is separated from his owner(s).
Any older dog with a house soiling problem should be examined by a veterinarian
and the owner should be able to give a detailed history of the color
and amount of urine (or stool) passed, the frequency at which the dog
needs to eliminate, changes in eating or drinking habits, the dog's posture
while eliminating, and whether the 'accidents' only occur when the owner
Medical conditions contributing to the house soiling problem should
be treated appropriately. If arthritis or painful movement is involved,
an owner may want to build a ramp to the outside so the dog does not
need to maneuver on stairs. Slick floor surfaces should be covered with
non-slip area rugs or other material. Areas in the house where the dog
has urinated or defecated should be cleaned with an enzyme cleaner. For
dogs who need to urinate or defecate frequently, owners may need to change
their schedules or find a pet sitter who can take the dog outside at
appropriate intervals. A dog's food may contribute to difficulty defecating,
and attempts should be made to determine if this could be a reason for
the house soiling. Other medical conditions such as diabetes mellitus,
bladder stones, or hormonal incontinence should be treated accordingly.
Some older dogs become overly sensitive to noise. One may think the
reverse would happen since many older dogs will acquire some hearing
loss. Cognitive dysfunction, immobility resulting in an inability of
the dog to remove himself from the source of the noise, and the decreased
ability of an older dog to manage stress may be factors contributing
to noise phobia.
It is important to identify which noises the dog may be afraid of. It
may be noises we can hear, such as thunderstorms, but remember that a
dog can hear frequencies humans cannot; the dog may be fearful of a sound
we can not hear. For this reason, also try to relate the dog's behavior
with other occurrences in the environment (e.g.; a train whistle, which
may produce some high frequency sounds).
Treatment of noise phobias can include medication, desensitization and
counterconditioning. For instance, if the sound is identified, play a
recording of the sound at a very low volume level and reward the dog
if no fear is displayed. Gradually (over days to weeks) the volume can
be increased and rewards given appropriately.
Stress in an older dog may translate itself into increased barking,
whining, or howling. This can occur during separation anxiety, as a means
to gain attention (if the dog can not come to you because of decreased
mobility, he may be asking you to come to him), or because of cognitive
The cause of the increased vocalization should be identified, if possible,
and medication should be given if appropriate. If the dog is vocalizing
in order to receive attention, he should be ignored. It may also be helpful
to use 'remote correction,' such as throwing a pop can containing a few
coins or pebbles toward the dog (not at the dog), which may startle him
and stop him from vocalizing. He should not associate you with the correction
or he may increase his vocalization just to get your attention. If the
increased vocalization is an attention-seeking behavior, review the amount
and type of attention you are giving the dog. Maybe you need to set aside
some time for you and your dog (on your terms).
Nocturnal restlessness - changes in sleep patterns
Some older dogs may become restless at night, and stay awake, pacing
through the house, or vocalizing. Pain, the need to urinate or defecate
more often, the loss of vision or hearing, changes in appetite, and neurologic
conditions can contribute to this behavior.
Any medical condition contributing to this behavior problem should be
treated. Again, remote corrections may be helpful, or it may be necessary
to confine the dog in a location away from the bedrooms during the night.
According to Pfizer Pharmaceutical, 62% of dogs age 10 years and older
will experience at least some of the following symptoms, which could
indicate that he has canine cognitive dysfunction (CCD):
- Confusion or disorientation. The dog may get lost in his own back
yard, or get trapped in corners or behind furniture.
- Pacing and being awake all night, or a change in sleeping patterns.
- Loss of housetraining abilities. A previously housetrained dog may
not remember and may urinate or defecate where he normally would not.
- Deceased activity level.
- Decreased attentiveness or staring into space.
- Not recognizing friends or family members.
When other factors
are ruled out (if decreased activity is due to an advancing arthritic
condition, for instance, or his inattentiveness due
to vision or hearing loss), and your veterinarian has determined that
your dog has CCD, a treatment for this disorder may be recommmended.
The new drug called Selegiline or
L-Deprenyl, (brand name Anipryl), although not a cure, has been shown
to alleviate some of the symptoms of CCD. If the dog responds, he will
need to be treated daily for the rest of his life. As with all medications,
there are side effects, and dogs with certain conditions should not be
given Anipryl. For instance, if your dog is on Mitaban for external parasites,
Anipryl should not be given. If you think your dog may have CCD, talk
to your veterinarian.
Adapting to new pets in the household
older dogs do not handle stress well, getting a new puppy when you have
an older dog showing signs of aging may not be the best idea. It is best
to get a new puppy when the older dog is still mobile (can get away from
the puppy), relatively pain free, is not experiencing cognitive dysfunction,
and has good hearing and vision.
Many of the behavioral changes we see in older dogs can be due to medical
conditions. If your dog's behavior is changing, have your dog examined
by a veterinarian. Your older dog is more easily stressed, so attempt
to reduce stress by making any necessary changes in routine gradual,
and decreasing the exposure of your dog to stressors. With patience,
understanding, and treatments recommended by your veterinarian, you can
help make your dog's older years a quality time for you and him.
