The time it takes for all dog hair and allergens to disappear from an apartment can vary depending on several factors such as the size of the apartment, the amount of dog hair and dander present, and the effectiveness of cleaning methods. Generally, it can take several weeks to a few months for all dog hair and allergens to completely disappear from an apartment.

Yes, an allergy test for dog mites and similar allergens can be done through a blood test. This type of test is called a specific IgE blood test, which measures the levels of antibodies produced by the immune system in response to specific allergens.

This blood test is a convenient alternative to skin prick tests for individuals who may not be able to undergo skin testing. **

E-commerce is not sustainable for several reasons. First, the increase in online shopping leads to higher energy consumption and carbon emissions from transportation and packaging. Additionally, the rise of fast fashion and disposable consumer goods in e-commerce contributes to environmental degradation and waste.

Finally, the convenience of e-commerce can lead to overconsumption and unnecessary purchases, further straining the environment. **

Books are generally considered more sustainable than e-books. While e-books do not require physical materials like paper and ink, they have a significant environmental impact due to the energy and resources required to produce and dispose of electronic devices. Additionally, the production and disposal of e-readers contribute to electronic waste, which can be harmful to the environment. On the other hand, books can be made from sustainably sourced materials and are often recyclable. Therefore, in terms of sustainability, books are generally the more environmentally friendly option. **
