Assessing The Reason For The Switch
Before you attempt to switch your dogs food, it is important to examine the reason behind the change. Changing your dogs food can be a complicated and gradual process, so before you embark on switching your dogs food, it is important to analyze the reason prompting your decision and assess whether or not it is worth it. Below are a handful of the most common reasons that a pet owner may switch their dogs food.
How Long Does Dog Diarrhea Last When Changing Food
During this transition week, youll be playing poop-detective. Changing up your dogs diet is likely to cause some stomach issues. Youll mostly see diarrhea, and maybe some vomiting or changes in appetite. Some dogs even develop skin irritations in response to diet changes. This is why its very important to approach this change gradually.
While skin and coat issues may take up to three months to resolve, gastrointestinal changes should correct much quicker. Your dog should have their symptoms resolve ideally within a few days of starting the new food, though this may take a bit longer. Mild diarrhea without any changes to eating and drinking habits is fine and will get better quickly.
If your pet is having moderate-severe consistent diarrhea, not eating or drinking, or losing weight, consult your vet right away.

Switching Dog Food: Should You Do It
There are a few situations in a dogs life that may justify a food change.
These include:
- A transition from puppy food to dog food
- A transition from dog food to a senior dog food
- A transition from kibble to a canned version
- A transition to a veterinary-recommended prescription diet
Many pet owners will switch from a puppy-specific formula to an adult dog food formula as their puppies grow up. A food change may also be recommended when dogs enter the senior phase of their lives as nutrient and calorie needs change.
If your dog was born with a medical condition, or develops one during their life, a change in diet prescribed to address the condition may help your pet to feel better and even live longer. For instance, if your dog has digestive problems, your veterinarian may recommend switching to a dog food for sensitive stomachs.

How To Choose A Dog Food
Choosing an appropriate diet for your dog is a complicated process. The sheer number of dog food options available is overwhelming. Unfortunately, there is no one diet that is best for every dog. Just like humans, dogs are individuals and their dietary needs vary depending on factors such as age, health, and personal preferences.
To make the process even more complicated, there are also a lot of myths about dog food on the internet. Many people fall victim to advertising campaigns or scare tactics warning them away from commercial dog foods. Fortunately, the World Small Animal Veterinary Association has published a guide entitled The Savvy Dog Owners Guide: Nutrition on the Internet to help pet owners decipher fact from fiction when doing their own research about dog food.
Learning how to read a pet food label can also help demystify the process of choosing a dog food. The information on a pet food label is guided by the Association of American Feed Control Officials . AAFCO is responsible for establishing definitions for many of the terms you will find on a bag of dog food. Understanding these labeling requirements can make it easier to identify which products are best for your dog. Look for the words complete and balanced diet on the label.

Observing Your Dog When Switching Foods
When switching your dog to a new food, it’s important you keep an eye on your canine companion to make sure it agrees with them. Watch for signs that the new food might not agree with your dog, such as diarrhea, vomiting, itchiness, or lethargy. It’s not unusual to have some changes in stool texture at first, but liquid diarrhea isn’t normal, especially if you gradually introduce the new food.
Over time, if the new food is agreeing with your dog, you should notice that they have a decent amount of energy , bright eyes, a healthy coat and skin, properly formed stools, and enthusiasm about mealtimes.
The right food can make more of a difference to your dog’s well-being than you might imagine.
