Bringing a rescue dog home is a major milestone – both for you and the dog. It is a transition from the streets or a shelter to a home, often in a new country among strangers. Everything is new, different, exciting, and often quite scary. Feeding is one of the most important ways to support your rescue dog during this transition.
In most cases, a rescue dog’s nutrition prior to adoption has been inconsistent and uncertain. Before entering a shelter, food may have been available only sporadically, if at all. Food provided at shelters is often of low quality – whatever could be sourced cheaply at the time.
A rescue dog’s digestive system is under pressure amidst change
The move and the massive life changes, along with the resulting stress, put the dog’s immune system and digestive tract to the test. Additionally, the dog typically undergoes deworming treatments, which place further strain on the gut.
The goal of the diet is to provide the rescue dog with as steady and calm a start as possible.
How to feed a rescue dog
Especially immediately after the move, it is advisable to choose a food that is as highly digestible as possible, with moderate levels of protein, fat, and fibre – so as not to unnecessarily burden the digestive tract. It's also wise to choose a food with a relatively simple composition, so the dog’s digestion isn't suddenly forced to process a vast amount of new ingredients.
The quality of ingredients is vital; high-quality protein has a balanced amino acid profile and is highly digestible, while carefully selected fat sources provide essential omega fatty acids crucial for the dog’s well-being. Despite a moderate fibre content, the food should ideally contain beneficial fibres, such as prebiotics that support gut flora and intestinal immunity, as well as psyllium to help balance stool quality. You may also consider a lactic acid bacteria supplement (e.g., Canius) to help the gut adapt to the new microbial environment.
In addition to the above, the food should contain sufficient protective nutrients—vitamins, minerals, and trace elements—as a rescue dog may have deficiencies in these. The antioxidant properties of many vitamins help support the dog’s immune system, and this group also includes nutrients that support skin and coat health.
Wait a little while before focusing on the dog's specific individual needs until the dog has settled in and adapted to its new environment. For example, it is not advisable to immediately give a thin dog the most calorie-dense, high-protein food possible, as food that is too "strong" can be taxing for an unaccustomed digestive system.
From Alvar Pet’s range, we typically recommend these complete meals designed for sensitive dogs, which perfectly meet the criteria listed above:
-
Digestion/Duck – a hypoallergenic and grain-free recipe; the sole protein source is duck.
-
Derma/Insect – a hypoallergenic and grain-free recipe; the sole protein source is insect protein.
-
Sensitive/Fish – a locally produced (Finnish), grain-free recipe; the sole protein source is fish.
Supporting the settling-in period
In addition to high-quality and gentle basic food, the transition phase can be supported with supplements and toppers:
-
Calm+ supplement: Alleviates stress and anxiety, supports the gut and immune system.
-
Chicken Topper: Supports hydration and adds palatability to the diet if appetite is lost due to nervousness.
-
Omega+ wild fish oil: Promotes skin regeneration and coat recovery.
These products, along with your chosen high-quality, gentle complete food, can be found in the Alvar Pet Rescue Box. The Rescue Box is a starter kit for a new, happy life forever-after – much like a typical puppy pack, but specifically designed for the needs of a rescue dog moving in.
Feeding a rescue dog: How often and how much
Start with small portions several times a day. This is easier on the dog’s stomach, and you can adjust the rhythm to your own daily routine as the dog settles in.
If the dog won’t eat: Stress in the midst of change can take away the appetite. Don't panic – give the dog time, space, and peace to eat when they feel like it. Extra treats and "tricks" make building a daily routine and a balanced diet harder and can stress the dog even more.
If the dog won’t drink: It is important to pay attention to sufficient hydration when a rescue dog arrives. If you notice the dog isn't drinking water, you can try flavoring the water with, for example, the broth from a Chicken Topper can. Including canned food as part of the diet also inherently supports hydration. It is also possible that the dog only feels brave enough to eat and drink at night – there is no need to worry about this.
If the dog has diarrhea: As mentioned, the changes and the move test a rescue dog’s gut and immunity. In mild cases, diarrhea can be treated at home by offering smaller, highly digestible portions, such as boiled chicken and rice. Additionally, you can try a supplement designed to soothe the gut (e.g., Dia-Tab). Ensure the dog stays hydrated and contact a veterinarian if symptoms persist or worsen.
If the dog is underweight: Give small portions several times a day so the stomach doesn't get too full at once. Caloric intake should not be increased too rapidly – the body needs time to adapt.
If the dog is overweight: Moving from shelter conditions to home life where exercise is regular, combined with quality food in recommended daily portions, is often enough to correct the situation over time without actual weight loss measures.
Resource guarding – when food is a great treasure
For many rescue dogs, high-quality food is a completely new experience. On the streets and in shelters, food may not have been a given, and they may have had to fight for it. It is therefore completely natural if a rescue dog protects their food bowl, treats, or toys. This is called resource guarding.
The best way to approach this is to always let the dog eat in peace, in their own space. Do not disturb them while eating, do not touch the bowl, and do not let others (humans or other dogs) approach the feeding area or interfere with the mealtime. Over time, the dog will learn that they don’t need to protect the food – no one is going to take it away.
If there are multiple dogs in the household: Treats, chews, and toys should always be given separately, in each dog’s own space. This allows the dogs to focus on enjoying their treats and play instead of potentially stressful guarding.
A fearful dog needs food near their "safe haven"
When a rescue dog moves in, it’s good to note that the planned feeding spot (typically the kitchen) might not always be the best place initially. A fearful dog still getting used to their new environment might not dare to eat or drink in a busy kitchen.
Place food and water near the dog’s own safe area – next to their bed, pen, or crate, or in another quiet and safe corner. This way, the dog doesn't have to push themselves or step out of their comfort zone just to meet their basic needs.
Gradually, as the rescue dog gets used to their new home, relaxes, and grows confidence, the feeding location and diet can be adjusted. In the beginning, the goal should be to keep changes to a minimum and introduce them gradually. High-quality, supportive nutrition provides an excellent foundation for a brave rescue dog’s happy and healthy life.
