Most dogs have no difficulty gulping any food that is put in front of them. Because of overeating and snacking, they are notoriously known for gaining weight quickly. And just like humans, dogs throughout their lives are susceptible to weight fluctuations.

For most dog owners, keeping their pup from becoming overweight is a constant battle. But what to do if the opposite is your main concern?  

How to tell if your pup underweight at all?

First thing’s first…  Instead of making important decisions about your dog’s health by yourself, always stay in touch with your vet.

The great news is there are some clear indications of a dog the must have some high-calorie meals to bulk up.

Among those are:

  • Bones sticking out, particularly ribs and shoulders
  • Worsen coat condition
  • Loss of interest in food
  • Lack of strength and objection to going for a walk
  • Diminished motivation almost the same as human depression

If you recognize any of these distressing symptoms, there is no need to panic instantly… Some breeds, for instance, have very low-fat stores. Visible bones in such dogs do not unmistakably point out that they demand to put on weight.

If you have any cause for concern, the practical thing is to visit the vet and talk with him about the possible plan of actions.

Why Is My Dog Losing Weight?

Weight loss is usually a sign of an underlying health problem. Dysfunction of organs is a common cause. Dogs with thyroid, liver, pancreas, and intestines issues are known to experience some form of weight loss.

Invasions of parasites can also lead to weight loss. Worms will use the food your dog consumes to thrive within their digestive tract. The essential nutrients will be stripped out of the food, leaving less for the pet’s well-being.

It’s critical to make a visit to the vet to get a better understanding of what’s going on with your dog. Your doctor will perform tests that can diagnose your dog so you can give them the treatment they require.

Since weight loss is a gradual process, for quite a while, it often goes unrecognized. Look at the shape of your dog from above. Do you see a smooth slope from the rib cage to the belly? Then all good.  But if it’s not, then refer to the symptoms mentioned in the previous section to confirm or reject your suspicions.

How to help a dog gain weight?

There is a contrast between giving a helping hand to your dog’s metabolism and supply him with an infinite amount of food so that he gets overweight. It’s just as dangerous as being too thin.

As with any adjustments in your dog’s nutrition, advising the vet first always pays. Instead of going for a radical overnight transformation, it is equally necessary to implement any changes gradually.

To put on weight, your dog needs to eat more calories than it burns off. This alone will guarantee that the pup gains weight as long as there is no pressing medical predicament.

What else can you help your pup with?

  • Feed your dog often: by supplying your dog smaller servings much more often, the pup may end up eating more than if you try to stick all the calories in one go.
  • Include high-calorie supplements into pet’s diet: there is no replacement for a staple diet of your pup. But treats and supplements have their place, especially in the cases when the dog needs some extra to gain weight.
  • Try a free-food approach: just leave food out at all times so that when your furry companion is starving, he can dig in.
  • Choose high-calorie foods, also rich in proteins: instead of concentrating purely on fat that can bring along associated health dangers, provide your pup with healthier options. Read on for some great examples.  

6 things to consider when helping your dog to gain weight

It’s a drastic change for any dog to add even a few pounds of weight. You don’t want to do anything that might potentially cause harm to pup’s well being. Keep the following things in mind to make sure your dog goes the weight gain journey healthily:

#1 Quality Over Quantity.

Your first impulse to add calories to the daily intake of your dog may be to add extra food to his bowl. While there may be a requirement for a small rise in food volume, too much of it may be a questionable strategy. Dogs are routine creatures. They also have delicate bellies. So food overloads may lead to stomach problems and disastrous bloat if your pup.

#2 Making the switch to a dog food designed to build mass is best.

These foods are stuffed with healthy ingredients. They are also dense in nutrients in most cases. So to see results, you will not have to make a massive difference in the serving size of your pup.

If you plan to increase your dog’s food supply, consider dividing it up over the day. Multiple small meals are much better than just one large meal. Your canine will be more energetic and have plenty of time to digest the food.

#3 Looking at the ingredients.

All-natural ingredients are used in holistic foods. They do not include preservatives, artificial colors or flavors, and tend to be filled with healthy fats.

This kind of food places substantial importance on top-notch components, and you will usually notice an excellent fat source on the top of the ingredients list.

The fact that holistic food includes “good” healthy oils is another of its benefits. Whether it’s fish oil rich in omega-3 fatty acids or high-caloric flaxseed oil – both of those are ensuring that your dog gets the necessary nutrients.

Protein is a crucial ingredient for muscle development that your dog needs. You should provide canine with food consisting of 30% protein at the very least. The larger this number, the better. Stay away from harmful by-products with less than the same amount of amino acids and stick to natural meat.

Another thing about reading the label of the pup’s food: select options with formulas you get. Clearly listed and named components are invariably better than vague, hard to pronounce, or questionable ingredients.

#4 Be patient and take things slowly.

Sudden changes in the diet are amongst the worst things you can do for your dog right now. The pup didn’t lose the weight overnight, so getting it back is a long process. Make diet modifications step by step. Begin with adding to standard pups food a bit of the new. Then add a bit more over a few days if a pup’s fine with adjustments.  This will give plenty of time for your pet’s digestion to get used to changes. That means fewer stomach problems and fewer messes for you to clean.

#5 Stay out of junk food.

Fatty treats just for the sake of boosting that calories number is as bad for dogs as for humans. Those are empty calories that won’t do your dog any services. While some fat is healthy, it can provoke even more problems.

You want your dog gaining that weight by growing more muscles, not increasing the fat storages.  Go for a protein-high choice with low levels of useless carbs. A small serving of such treats is a good idea.

#6 Don’t forget about the supplements.

Those will quickly turn your dog’s regular food in more nutritious and sometimes more appealing food option.  These products are accessible in different kinds to satisfy your dog’s needs: pills, treats, or even liquids. But like with all other supplements, it makes sense to ask your vet first and strictly follow the directions for serving to assure that your canine grows a healthy weight.

Overall, there are many methods to support your dog in gaining healthy weight. And it’s completely possible for your furry companion to build muscles on a high-calorie diet instead of having stomach problems.

How to put weight on a dog with a sensitive stomach

“Sensitive stomach is a generic and vague term,” says veterinarian Dr. Patrick Mahaney.

Such condition can result in anything from gasses to diarrhea.

And it’s common for dogs partly because they are very curious and are exploring the universe through all their senses, including taste.  Some breeds like the Scottish Terrier and the Yorkie are more susceptible to this. Older dogs and puppies are also at a higher risk here. And that’s the reason why sometimes the dog’s owners are struggling with never-ending quest to find a proper diet that their pup will accept and enjoy. And if you also have to fix the issue of putting on weight this search gets even more perplexing. Well try this:
