Although it may seem like a totally basic question, the truth is that there are people who are somewhat lost in this matter, and there are many legends and ideas about what to do in the first months of the dog's life. During this period it is necessary take extreme precautions, since your immune system is not that strong, and if you get sick we can lose it.
The bathroom also has to do with the possibility of lowering the dog's defenses, but there are nuances when deciding when can we bathe the dog. The right time and frequency depends on each case, although there are general guidelines that we must take into account when bathing the dog.
When the mother is nursing the puppyIt should not be washed, since the smell of the dog is what makes the mother recognize it as her own. In the case of stray cats, there are even cases of mothers who reject their kittens if someone has touched them, because they no longer smell the same. In this way, you have to wait for them to pass this stage.
On the other hand, there are many who ask if they can bathe even if they do not yet have all vaccines. Yes you can, but be careful, because it is not recommended. The reason is that if we do it wrong, the bath can make the dog cold and sick, and hence it is avoided until it has the strong defenses to face these situations.
If your dog has gotten dirty and it doesn't fit no choice but to bathe him Because you do not give it clean or with the typical baby wipes, you can do it, but in a controlled environment, with warm water, in a bathroom where it is not cold and then drying it completely with the dryer.
