Solutions to Golden Retriever’s bad mouth:

1. If it is caused by food residue, you can use a special toothbrush for Golden Retrievers to brush your dog’s teeth, or use a pet-specific rinse aid. Using saliva on dogs can improve the bad breath situation.

2. If it is caused by vitamin deficiency, bad breath can be eliminated by supplementing the deficient vitamins.

3. If it is caused by gastrointestinal digestion, you can use probiotics to regulate the golden retriever, and go to the pet hospital for gastrointestinal treatment in time.

4. If it is caused by oral disease, you need to find the cause of the golden retriever's oral disease, and then use oral sprays, anti-inflammatory drugs, etc. to treat the problem.

The reasons why Golden Retrievers have bad mouth:

1. Because the teeth are not brushed regularly, a lot of plaque and even dental calculus will remain on the Golden Retriever’s teeth. Then dental plaque and dental calculus will cause a very bad smell in the dog's mouth.

2. Because the Golden Retriever eats some food, its stomach cannot digest it or does not digest it well, which will cause it to have bad breath.

3. Stomatitis or other oral diseases in golden retrievers can also cause bad breath in dogs.

4. A lack of vitamins or trace elements in Golden Retriever’s body can also cause bad breath.
