Choked Up On A Bone Or Some Toys

Canines love to chew on certain chewable toys or bones. It is good but it can turn out to be brittle. Because these objects are breakable, brittle pieces can get stuck in the canine’s throat and cause the canine to throw up.

Human Food

Many dog owners think that if some food is healthy for them, it is the same for canines. However, canines have very different nutritional needs than us. If your canine has consumed some of your food then there is a chance that he will vomit it out.

The canine’s body does not accept human foods like pizza, sugary candy, chips, pies, chocolates, etc, and it vomits it in the form of hard white chunks. To prevent this, you must avoid feeding these food items to your dog and keep an eye on your dog as well.

Stomach Acid Buildup

If your canine is throwing up white hard chunks, one of the common reasons is stomach acid buildup. In this scenario, the dog throws up white chunks because his stomach is empty or has little food.

When a canine has a lot of stomach acid, its vomit mainly contains foam with saliva and some gastric juices. The mucus lining becomes irritated and the canine vomits foam or froth. Moreover, in a few cases, it also contains unidentified white hard chunks.

If your canine has stomach acid buildup, you may notice symptoms like coughing, swallowing, hiccupping, and licking the floor. You can get rid of stomach acid buildup by feeding the canine enough food each day
