Changes You Can
Expect As Your Dog Gets Older
Your dog's body takes a beating throughout his
life. Muscles are pulled, joints stressed, and organs scarred by
infection. Cell structure breaks down, decreasing the efficacy of
organs and tissues. All of these traumas cause abnormal cell
development, which in turn create tumors and arthritic conditions.
On the outside, he can appear as healthy and active as any younger
dog, but inside his organs are not functioning as efficiently as
when he was younger.
For example, if the kidneys begin to
deteriorate, they can continue to function with only 40 percent of
the tubules (the part of the kidney that breaks down nutrients from
urea) working. Your aging dog will continue feeling fine and
behaving normally. However, this can take a quick turn for the
worse if a kidney disease continues to deteriorate. This can happen
slowly or what seems like overnight. Until this happens, the only
difference in your dog will be his need to urinate more often.
Otherwise, there is no sign of a problem. As he ages, you need to
ensure his complete health by adjusting his diet, exercise, and by
keeping a close watch on his behavior. In fact, you'll notice many
problems first through behavioral changes before his body shows the
outward signs.
Changes in appetite, a lack of desire to move
about, or overall grouchiness are usually symptoms of a deeper
problem. Your dog's muscles will remain strong, provided he
exercises. The more he does as a youngster, the more he can do as
an oldster. You must keep in mind, however, that he cannot tell you
he doesn't want to go those extra miles with you. All he wants is
to be with you and please you, regardless of how he feels. His
muscles may still be strong at this point, but his internal
workings are no longer operating in prime condition.
Your dog can still remain physically healthy
with a little less exercise - maybe two or three miles instead of
five or maybe you can do the run on softer ground instead of hard
concrete. The musculoskeletal system will usually exhibit arthritic
changes as he turns into a senior dog. Arthritis is formed through
changes in the joint bones, a reduction of cartilage, and a
thickening of the synovial fluid between the joints. Often,
inflammation can cause more irritation and lameness. Not only will
the arthritic changes cause pain in the joints, but they will also
cause atrophy in the muscles because your dog will not want to move
around. The muscles begin to get loose and hang off the bones. This
is most obvious along the spine, chest, and hind legs.
As the muscles atrophy, the skin will appear
looser or baggy. Overall, your dog becomes a different dog as his
senior years take over. He moves more slowly, picks at his meals,
and may bump into things that he can't see. However, the biggest
change will be in his behavior. As he ages, he may not only slow
down, he will also become less excitable in general. He will still
greet you with a wagging tail, but not jump on you or perform
aerial leaps when you come home. When going out, he'll walk to the
door and wait patiently as you search for his leash - no more
racing in circles, barking excitedly, and jumping about.
