If a dog has a fishy smell, it will surely become unpleasant for its owner as well, because we are talking about a bad smell. To figure out where it came from, we would have to examine the animal literally from head to toe, at least in theory.
1. Dental problems
The source of the fishy odor may be in the mouth, or it may be caused by some dental problems. If the four-legged friend allows this, his teeth, as well as his gums and palate, should be examined. Their care always requires a veterinarian.
In addition to bad teeth or gingivitis, there may be some food debris stuck between the teeth, which has begun to decay. After removing this, it is worth brushing the dog's teeth. However, regular brushing is essential to protect the health of this tooth.
In addition, there can also be a harmless reason why your dog's breath may smell bad: if he has been fed fish or food containing fish oil.
2. Problems with the olfactory gland
If your dog has a problem with his olfactory gland (it doesn't empty itself, which is why it's full or inflamed), it can also produce a fishy odor due to the secretions in it. This problem is indicated if the dog licks her butt a lot or often drags her along the floor, but the area can also be seen visually if the glands are full or the area is red and irritated. Difficult defecation is also an indicator, as is the animal's unwillingness to sit (due to pain). Cleaning the olfactory gland is a veterinary task, and a specialist can show you what to do with it next time.
In some dogs, these glands are emptied as a result of fear or stress, so the origin of the fishy smell also depends on the situation.
