Of the primasry fasctors that help control aging and memory, balanced nutrition and modest amounts of exercise are the most important for ourselves and the pets with whom we share our lives.
Functional foods are those that provide optimal nutrition and body function and improve the memory and cogniftive activity of aging. These include vitamins E and C, and resveratrol (acting as antioxidants) along with a mixture of fruits and vegetables to reduce free radical damage. Also important are alpha-lipoic acid and L-carnitine as they are cofactors of the mitochondria of all cells. Mitochondria are responsible within cells for providing for their respiration and energy production.
Exercise in modest amounts should be given along with tasks for the pet to learn and perform.
Omega-3 fatty acids are essential for dogs especially as they age because they help improve brain health and function and slow the loss of cognitive function associated with aging.
The requirement for essential nutrients increases not only during periods of rapid growth or reproduction but also in geriatrics, because immune function and bio-availability of nutrients generally wanes with aging.
Top 10 Great Foods for Brain Health and Memory
- Leafy greens (folate, vitamin B 9) - kale, spinach, collard and mustard greens

Canine Cognitive Dysfunction
Clinical Signs of Cognitive Dysfunction
- Confusion/disorientation in familiar surroundings
- Increased sleeping/insomnia
- Loss of interest in people and events
- Forgetfulness of housetraining habits
- Failure to recognize familiar people and animals
- Wandering aimlessly/pacing
- Loss of appetite/forgetting to eat
- Staring into space
- Decreased activity level
- Lack of response to name/commands
- Failure to pay attention
Nutrients of Genera Benefit for Cognitive Dysfunction
- Milk thistle and SAMe (S-adenosylmethionine)
- Medium-chain triglycerides (MCTs)
- DHA and EPA omega-3 fatty acids
- Avoid glutens
- Avoid carbohydrates with high glycemic index
Silibinin (milk thistle extract) prevents impairment of both short-term and recognition memory
- prevention for cancer as well
- works as antioxidant, protects brain from oxidative damage
SAMe (S-adenosyl methionine) improves neuron membrane fluidity
- increases serotonin and dopamine metabolites
- reduces effects of depression in people
- may help human Alzheimer’s patients
Phospholipid choline is critical for cell membrane structure and function
- increases production of acetylcholine
- helps reverse signs of cognitive and other neurological disorders of aging pets
Medium -Chain Triglycerides, like coconut oil, break down and absorb rapidly, unlike fats; quick source of non-carbohydrate energy
- readily cross blood-brain barrier, supplying 20% of brain energy requirement
- important for ketone production
- help body use omega-3 fatty acids more efficiently
- helps age-related cognitive decline by providing alternative source of brain energy
- give berries their rich pigment; antioxidants; also benefit cognitive health of senior dogs
- most potent is aronia, the chokeberry. Greater antioxidant than all other berries; anti-cancer; anti-bacterial, anti-viral and even anti-diabetic; and anti-inflammatory
- protect brain function in geriatrics and those with gluten intolerance by avoiding wheat, barley, rye, oats unless labeled gluten-free, kamut, spelt, farro, and couscous
- linked with impairment of brain function, including learning disabilities, attention-deficit-hyperactivity disorder, and memory problems
- gluten sensitivity may manifest exclusively as a neurological disease
Avoid Carbohydrates with a high glycemic index (GI)
- impaired glucose metabolism caused by sugary foods can promote brain starvation, leading to memory problems, like canine cognitive dysfunction
- foods with high GI can also lead to hunger-related behavioral problems
- simple carbohydrates digest and absorb quickly (hence rapid rise and fall in blood sugar concentrations), so pets feel hungry again quickly
The history of veterinary transfusion medicine began in 1665 with the first reported transfusion of canine blood. From that time to the present day, whole blood and blood components have been used to treat many disease states and for surgery in veterinary medicine.
The need for establishing local, regional, and national blood banking services for animals has become apparent in recent years with the development of sophisticated medical and surgical support for animals that parallel those of human medicine. At the same time, the emergence of pet animal health insurance programs helps to provide a means of financial support for advanced critical care. Despite these efforts, however, most of the world needs are not being met today. The demand exceeds supply and individual programs still need to be standardized to ensure safety and efficacy.
Present and Future Needs
Until recently most veterinarians gave whole blood transfusions from donors that had not been blood typed or cross-matched as emergency life-saving measures to combat traumatic or surgical shock, severe anemia, hypoproteinemia, and bleeding. This would usually be the animal’s first transfusion. Today, while animal blood typing reagents and cards are commercially available for the major blood group antigens of dogs (DEA 1) and cats (A, B), more complete typing services and reagents are provided only by veterinary researchers and certain blood banks.
Need for Compatible Blood
It is important that veterinarians use typed, compatible blood whenever a transfusion is given.
For cats, cross-matching the recipient and donor beforehand is an essential standard of practice, to avoid serious or life-threatening transfusion reactions. Further, hemolytic disease of the newborn kitten can occur with type-incompatible matings, and result in significant neonatal morbidity and mortality. A parallel situation is well known in people, and also occurs in other species like the horse and pig.
All cats have naturally-occurring antibodies against the other blood type, such that strong incompatibility reactions are seen when blood type B recipients receive blood from type A donors [because type A cats have potent anti-B antibodies.] Knowing the blood type of in-clinic feline donors (and recipients) is also advisable.
Dogs, in contrast to cats, do not have naturally-occurring antibodies against other canine blood group antigens. However, because it is usually impractical from an economic and timing standpoint to determine the blood type of dogs requiring immediate transfusion, most blood bank programs depend upon in-clinic or local canine donors that have been pre-screened. The donor dogs are selected for overall health and vigor, ease of bleeding and docile temperament, and they should have what is termed the "universal donor" blood type [negative for all canine red cell antigens except DEA 4, which is essentially present in all dogs]. This means that their red blood cells do not carry any of the surface antigens associated with transfusion reactions or incompatibilities.
Another issue surrounds the transfusion of incompatible blood to breeding females, as it poses a potential risk of immunologic sensitization (alloimunization). If a sire also mismatched in blood type is subsequently mated with this female, hemolytic disease of the newborn can be exhibited by some of the puppies. This can be a significant cause of the "fading puppy syndrome" in dams that have had more than one litter, but can be avoided by blood typing the sensitized dam and selecting only type-compatible sires for future breedings.
Need for Safe Blood
A second, but equally important aspect of veterinary transfusion medicine, is to ensure that all blood used for transfusion is properly screened for blood-transmitted infectious diseases. In 2005, an expert task force of the ACVIM concluded that safety issues are of major concern, because about 60% of blood transfusions given in private practice settings use blood from local animal donors (non-commercial source) that may not be blood-type compatible and are usually not screened for infectious diseases. This practice poses a significant potential liability for malpractice should an adverse transfusion event occur.
Blood Component Therapy
Whole blood is no longer the treatment of choice, nor is it desirable for the primary therapy of most veterinary transfusions. Processing freshly collected blood into several clinically useful components is a more cost-effective, efficient and safer use of this precious life-saving resource. The most commonly used blood components in veterinary medicine parallel those in human medicine: packed red blood cells and fresh-frozen plasma. The red blood cells are primarily used to treat acute blood loss anemia from trauma, surgery, or acute hemolytic disease, and for chronic anemias caused by internal (hookworms) and external (fleas, ticks) parasites, bone marrow failure and chronic hemolytic disease. Fresh frozen-plasma is used mostly to treat or control bleeding disorders and to provide other plasma proteins and globulins to help alleviate or protect against acute or chronic infectious diseases, such as parvovirus infections.
Hemopet, the Non-Profit Canine Blood Bank
Hemopet, began in 1991 as a US federally registered non-profit, charitable organization. Our licensed facility houses a colony of healthy, canine blood donors, all of which have the universal blood type (DEA 4), are screened for an inclusive list of disease pathogens, and are current on all vaccinations. These dogs are all Greyhounds rescued because they were unsuitable for the racing industry. We maintain around 200 donors at present in our large facility in Garden Grove, and have initiated a novel rescue-donor-adoption program for them. All the dogs have been neutered and receive on-site 24 hours-a-day veterinary care and maintenance. After serving up to a year in the donor program, they are adopted out as family companions. https://www.hemopet.org/
Hemopet’s full-service blood bank provides state-of-the-art blood components and supplies for transfusions to veterinary clinics. These include: Canine whole blood, canine packed red blood cells, canine fresh-frozen plasma, canine platelet-rich plasma, canine cryoprecipitate, canine cryo-supernatant, canine frozen plasma, disposables and speciality products for transfusion, transfusion consultation.

Over the years, Professor Ronald Schultz has been a pioneer in creating vaccination guidelines for our pets.
So when Professor Schultz comes up with the statement “Be Wise and Immunize, But Immunize Wisely”, what is the take home message?
A Concept Change for Pet Vaccination
The routine administration of vaccines in dogs and cats has been one of the most significant factors in the consistent reduction of serious dog and cat infectious diseases.
Although all veterinarians agree vaccines are necessary, the frequency in which some of them are given, is now debated.
It is known that dogs and cats, after vaccination, often maintain protective antibody to what is called the “core diseases” - Canine Hepatitis, Parvovirus and Distemper and Feline Panleukopenia, Herpes and Calici Virus for three or more years. So, our dilemma is knowing that we may not need to revaccinate our pets for core vaccines, how can we know that the antibody levels of our pets through vaccination are indeed adequate?
Titer Testing to Determine Protection for Our Pets
Antibody or titer testing can be used to show levels of protection after vaccinating our pets with core vaccines.
Therefore, when an antibody is present, there should be no need to revaccinate.
How Often to Titer Test?
Professor Schultz has offered the following advice:
“Neither a titer nor annual vaccination is necessary every year because of the core vaccines’ duration of immunity. However, a blood sample taken yearly from an animal for a titer check is preferential to an unnecessary vaccination as a vaccine may cause harm.”
The Canine and Feline VacciCheck are Core Vaccine Tests
One of the titer tests available and, easily performed by vets, in their clinics, is VacciCheck.
VacciCheck tests for your pet’s antibodies and can determine if a dog or cat needs an additional core vaccine vaccination. This may save the dog or cat unnecessary vaccinations.
VacciCheck also confirms if puppies or kittens have received immunity from vaccination.
Also unique about VacciCheck, results can be received on the same day.
So vets now have a quick and simple test that can be performed in their clinic, at a reasonable cost to the pet owner.
It is no wonder that The World Small Animal Veterinary Association recommends in clinic titer testing, such as VacciCheck.
