Aiding in the growth and repair of a Dog's body tissues means your Dog's diet requires Protein.
Dogs need a higher proportion of Protein in their diet compared to humans do.
So, make sure their diet includes sources of:
Chicken
Turkey
Beef
Fish

In addition to these proteins, carbohydrates are also essential.
Carbohydrates, in addition to Protein, are a vital component of a Dog's diet.
Excellent sources of carbohydrates are:
Rice
Potatoes
Vegetables
This will provide your Medium-Sized Dog with the energy it needs for daily activities, supporting its active lifestyle.

Healthy Fats For Your Dog.
Healthy fats are an important part of a Medium-Sized Dog's diet.
They support the health of:
Coat
Skin
Brain Function
And can also help in the absorption of specific Vitamins.
You can find healthy fats in:
Fish Oil
Flaxseed Oil
These are healthy fats that are particularly beneficial to add to your Dog's diet.
However, please remember that your Dog should consume fats in moderation, as excess fat can lead to obesity and related health problems.

Supporting the Immune System.
Vitamins and minerals, although required in smaller quantities, are essential for numerous physiological functions.
Including Vitamins in a Medium Dog's Diet will help support
Immune systems
Bone health
Metabolic processes.
Many premium Dog Foods are enriched with essential Minerals and Vitamins to help with a Dog's health.
However, incorporating natural sources such as:
Fruits
Vegetables
These will also enhance a Dog's Diet and provide additional Nutritional benefits.
Be aware, though, that if you are incorporating fruit and vegetables into your Medium-Sized Dog's Diet, not all are safe for your Dog to eat.
Fruits and Vegetables That Are Unsafe for Medium-Sized Dogs
Although many fruits and vegetables can provide valuable vitamins, minerals and fibre, some are unsafe for dogs and should never be included in their diet.
Even medium-sized breeds, which can generally tolerate slightly larger portions than small dogs, are still vulnerable to the toxic compounds found in certain foods. Understanding these risks helps explain why it is so important to know which fruits and vegetables to avoid, and can help prevent serious illness and expensive veterinary treatment.
Grapes and Raisins
Grapes, raisins, sultanas and currants are among the most dangerous fruits for dogs.
A small amount can cause kidney failure, although the exact toxic substance is still unknown.
Symptoms may include vomiting, diarrhoea, tiredness, loss of appetite and reduced urination.
Seek immediate veterinary attention if your dog eats any of these fruits.
Avocados
Avocados contain a natural toxin called persin. While in general, dogs are less sensitive to persin than some other animals, it can still cause stomach upset, including vomiting and diarrhoea.
The large stone also presents a choking hazard and may cause an intestinal blockage if swallowed.
Cherries
The flesh of a ripe cherry is not considered highly toxic, but the stones, stalks and leaves contain cyanogenic compounds that release cyanide when chewed.
This can interfere with oxygen delivery throughout the body.
Cherry stones may also become lodged in the digestive tract, creating a potentially life-threatening blockage.
Unripe Tomatoes and Tomato Plants
Fully ripe tomatoes are usually safe in small amounts, but green tomatoes, stems, and leaves contain solanine and tomatine.
These substances may cause digestive upset, weakness, lethargy and, in severe cases, heart or nervous system problems if eaten in large quantities.
Wild Mushrooms
Some wild mushrooms contain toxins that can damage the liver, kidneys or nervous system.
Because it is difficult to distinguish poisonous mushrooms from safe varieties, dogs should never be allowed to eat mushrooms found outdoors.
If you suspect your dog has eaten a wild mushroom, contact your vet immediately.
Onions
Onions contain compounds that damage a dog's red blood cells, potentially leading to anaemia.
They are harmful whether raw, cooked, dried, or powdered, and repeated small amounts can be just as dangerous as a single large serving.
Signs of poisoning include weakness, pale gums, rapid breathing and lethargy.
Garlic
Garlic is part of the onion family and contains similar toxic compounds, though they are generally more concentrated in garlic.
Excessive amounts can damage red blood cells and lead to anaemia.
Some dogs may also develop stomach irritation after eating garlic.
Leeks
Leeks contain the same harmful substances found in onions and garlic.
Eating them can damage red blood cells and cause digestive problems.
They should not be offered as part of a dog’s diet.
Chives
Chives are another member of the allium family and are toxic to dogs.
Even small quantities can contribute to red blood cell damage, particularly if consumed regularly.
Raw Potatoes
Raw potatoes contain solanine, especially when they are green or have begun to sprout. Solanine can cause stomach upset, weakness and changes to the nervous system.
Plain, thoroughly cooked potatoes are much safer when served in moderation, provided they are free from butter, salt or seasonings.
Rhubarb
Rhubarb leaves contain high levels of soluble oxalates, which can interfere with calcium levels and potentially damage the kidneys.
Signs of poisoning include drooling, weakness, tremors and difficulty walking.
Keeping Your Dog Safe
The safest approach is to introduce only dog-friendly fruits and vegetables in small amounts while avoiding those known to be harmful.
If you are unsure about a particular food, consult your veterinary surgeon before offering it to your dog.
A balanced, nutritionally complete diet remains the best way to support your medium-sized dog's long-term health, energy levels and overall wellbeing.
A Well-Balanced Diet.
Getting your Medium-Sized Dog's diet right has numerous benefits.
Shinier Coat
Healthier Skin
Brighter Eyes
Increased Energy
Optimal nutrition, including a well-balanced diet, aids in:
Digestion
Healthy Weight
A well-balanced diet reduces the likelihood of OBESITY and associated diseases, such as DIABETES and JOINT PROBLEMS, promoting your Dog's long-term health and wellbeing.
It can also support a Medium-Sized Dog's IMMUNE SYSTEM, making it less susceptible to illness and more able to recover quickly if it does get sick.
Final Thoughts
Providing a balanced diet is not just a task, but a crucial responsibility for the Medium-Sized Dog's welfare.
It's not just about feeding them, but about nourishing them with the proper nutrients in the right proportions.
Every Dog is remarkable, and their dietary needs can vary significantly.
A Dog's Diet should be subject to factors such as
Breed
Activity Level
Health
Age
It's a great idea to reach out to a Pet Nutritionist to help create a Diet Plan that's just right for your Dog!
They can provide you with the support and guidance you need, bringing you peace of mind knowing your Dog is getting precisely what it requires.
