Shovel excrement officer to do external deworming for the dog, there were some unexpected situations, so that the shovel excrement officer thought he had done a "fake" deworming, what is going on? Dr. E is here to tell you.
I can't stop scratching after taking the medicine.
Conventional in vitro anthelmintic drugs act on the body surface, and it takes 2 to 3 days to completely kill the insects; the mechanism of action is also to make the parasite die after nerve excitation, and the parasite will struggle in the process of death, which will cause the dog to scratch, which is actually a manifestation of the drug effect, so the dog may still have itching after medication.
Worms were found after deworming.
? 1 The worm has not yet been exposed to the drug.
Common external anthelmintics (drops) are spread from the local to the whole body with sebum, and the insects need to be exposed to the ingredients of the liquid medicine to be killed. If there are more adults on the dog's body surface and they are attached to the dog's hair, they can't contact the drug until they suck blood or eat dander, and then they are destroyed, so if there are still worms after deworming, it may be that they have not been exposed to the drug yet.
2. Incomplete deworming of the environment
Some parasites will lay eggs on the dog's body surface, and then as the dog walks, the eggs will fall into the living environment. The eggs will hatch into adults and then run to the dog, so you will still see insects. Fleas are powerful parasites, which can lay up to 50 eggs a day. The speed and number of reproduction are quite amazing! So the environment is very important.
Did not choose the right anthelmintic?
If the drug is not symptomatic, some external deworming drugs are only effective against some parasites, such as tick repellent drugs, but it is possible that the dog is infected with fleas or lice.
There were adverse reactions after in vitro deworming.
1. The type of slopping and rolling
The itching caused by the death throes of parasites can make dogs roll around, and the smell of drugs is irritating, because dogs have sensitive noses and feel strong discomfort, so they want to rub off the smell of drugs on their bodies and run around the house crazily. This is a normal phenomenon, don't worry too much, the dog will soon return to normal.
Lacklustre type
Some internal and external anthelmintics can be absorbed into the blood to kill intestinal parasites, so it can cause gastrointestinal discomfort, loss of appetite and poor spirit, which is also a normal reaction, generally 1-2 days later, it will heal itself.
