Dogs experience similar age related changes as people such as diminishing senses, cognitive ability and arthritis. This article will explore some common changes and how we can help them.
Diminishing senses:
Because blindness and hearing loss can create anxiety in pets and affect the human animal bond, which then affects their life quality, strategies to cope with blindness and hearing loss in pets should be considered. Loss of smell, touch and taste are rare as far as we know in pets.
Vision Loss: Cataracts and acquired vision loss all contribute to poor vision. People may notice this more at night or when walking outside where the dog is less familiar with its surroundings. Throwing a small object or setting up a little obstacle course may help these changes come to light. Blindness can occur gradually or suddenly. Treating the underlying cause is important although for some conditions there is no treatment. How rapidly blindness occurs often dictates how well our pets adjust. Most dogs adapt and live normal happy lives. Vision is not a dogs primary sense and most adjust their hearing and sense of smell to accommodate.
Helping a blind pet cope: Unsafe areas in the house need to be blocked off (pools, stairs, etc) You can place bells on other pets in the house. If you need to rearrange furniture do it very gradually. Teach your pet verbal cues when approaching unsafe areas like stairs or corners. Cues like “slow down”, “wait”, “Watch out” They can still play with fetching toys and balls. Use ones that make noise or a kong that you can stuff with smelly treats like peanut butter. Halos and Visors (Optivizor): help prevent bumping their head into things. Living With Blind Dogs by Caroline Levine is a great resource.
Hearing Loss: Hearing loss starts with middle and high frequency sounds. People often interpret early hearing loss as behavioral or they say their pets have “selective hearing”. They generally do not recognize hearing loss until it is advanced. It is usually only detected when there is loss on both sides and it is almost complete. Hearing loss in pets is usually very gradual. Communication with pets can become very frustrating and they also will startle very easily.
Helping a pet with hearing loss: Approach your pet within their field of vision to try and diminish startling them. If your pet is sleeping or resting, try putting their hand in front of their nose to allow your pet to smell you before you actually touch or startle them. Using a familiar scent may aid in awakening a deaf pet. If they still do not awaken, then softly touch a non-painful part of the body. Avoid the face. Train your pet to understand hand, arm and body signals. It would wise to teach your dog in this manner prior to the onset of hearing loss. A flashlight can be used to get their attention and to guide them. Some pets can actually still sense vibrations so stomping feet on the floor or clapping hands can also be used effectively. Deaf pets should be leash walked only and supervised when they are in a fenced yard. They should wear a tag saying that they are deaf in case they get out.
Cognitive Dysfunction and Sleep Disturbances:
Cognitive dysfunction, similar to dementia, has a subtle onset but is progressive and will result in substantial decline in a pets overall quality of life. People rarely bring the early signs of cognitive dysfunction to our attention because they are very subtle. Symptoms often mimic other age related conditions like pain and metabolic disease. These need to be ruled out first. Cognitive dysfunction is a diagnosis of exclusion. We know this, as in human Alzheimer’s disease, changes may be occurring for years before they become recognized. Any behavior changes should be discussed with your veterinarian during senior wellness visits as there is the possibility of slowing progression through a combination of supplements, diet and behavior modification. Treatment is variable depending on what symptoms are being expressed. Here are some suggestions that can help any aging pet:
Home environment: Try and keep the environment as low stress as possible. Change furniture placement only gradually. May need to close off doors by placing baby gates in areas dogs can be hurt like stairways. Placing baby gates or other obstacles may also help with nighttime wandering. Food and water dishes should be placed in easily accessible areas and that area not moved.
Consistent daily routine: This helps bring stability in an increasingly confusing world. Keep timing for feedings, treats, walks and play sessions as predictable as possible.
Exercise: Consistent gentle exercise is good for geriatric pets in that it improves mobility, helps maintain muscle mass and is mentally stimulating. Endorphin release associated with exercise may also actively calm the pet and decrease anxiety. The intensity and duration of exercise may need to be shortened however. These might include low impact walks, limited time fetch, swimming, hide and seek, range of motion exercises, massage.
Mental stimulation: Asking pets to figure out a new concept or perform a new task can be an excellent tool in the fight against progressive cognitive decline. This can be as simple as encouraging your pet to take new routes on a walk. People can purchase novel toys that encourage sensory stimulation. They can reward their pet with food when using brainteaser type toys. Examples of toys and puzzles can be found at https://dogdementia.com/
Rotate favorite toys: Work with obedience training spending a few minutes each day reinforcing these concepts.
Love: Unfortunately with many of these pets the human animal bond has been broken because of the frustration that can be felt living with a pet with cognitive dysfunction. It is worthwhile to spend a few minutes of intentional love and affection every day. This entails times simply enjoying each other‘s company rather than attending to needs.
Arthritis in Aging Dogs: Approximately 25 percent of dogs are diagnosed with arthritis in their life time, and as many as 60 percent of dogs have radiographic evidence of it. Arthritis is due to years of wear and tear on the joints or due to a previous injury. Arthritis can affect any age, sex, and breed of dog. Lameness and difficulty rising are the most common signs. They may happen once in a while and get worse over time. Stiffness is common after periods of rest. Stiffness and lameness may decrease when the dog warms up a bit with some activity. Lameness often gets worse after periods of overexertion. Radiographs should be taken to rule out other painful conditions and to identify the location and severity so appropriate recommendations can be made for treatment. Most often a multimodal approach is taken that includes supplements, exercise, pain medication, weight loss where needed and physical therapy exercises which can often be done at home. Laser therapy and acupuncture are also options for older pets.
Declining organ function: The most common organs to exhibit age related organ dysfunction are the kidneys and liver. Other organs, like the heart, lungs, intestinal tract, adrenal glands, thyroid and brain are also commonly affected. Signs of organ dysfunction are often identified on biannual exams and lab work. Treatment is of course dependent on the organs involved and the severity of the problem.
I would like to end with this quote: “Just because he’s getting old doesn’t mean that we just stand on the sidelines and let him get old. There are things we can do to intervene and improve the pets ability to function and improve its quality of life.” Dr. Marsha Reich
