House paint, varnishes, primer, and other decorative products or protective solvents come in many varieties and most of them are dangerous to house pets like dogs and cats. Water based paints including latex, tempera, and poster paints are also harmful to dogs and cats. Older 
paint products may also contain lead; even lead-based paint was banned in 1977 by the U.S. Consumer Product Safety Commission (CPSC). All these types of paints are really harmful to your pets and you need to take preventive measures before you start painting your house.
Pets are naturally curious in nature and they may walk through your painting supplies, work area, or on a freshly painted surface. During this time, your lovable pet may intake a small amount of paint while grooming or licking off fresh paint. In such cases, if your dog or cat is exposed to paint through licking or grooming, serious health hazards could occur. This is the reason you need to keep your house pets away from paints and varnishes at all times whenever possible.
There are few things that you can do to prevent your house pets being harmed by paints.
Store Paint Products Safely:
It is important to store all your paint products including paint jars, brushes, roller, and other instruments safely out of your pet’s reach. You should be aware of any unwanted events when your pets may reach to the paint products accidentally and be affected by the paint or varnish poisoning.
Remove Paint Wastes & Cleaning Supplies:
Another important thing is to properly dispose of paint wastes as well as other cleaning supplies. It is always important to keep your house environment safe and if the case of any hazard, please call your veterinarian or pet poison helpline number in your locality. Pet poison helpline generally available 24/7 for pet owners that require assistance for treating a potentially poisoned pet.
Keep Your Pet Outside Until The Paint Is Dry:
You can also keep your pet cat or dog outside the newly painted room until the paint is properly dry. It is also important that area is properly ventilated. In order to do this, you can keep your pet in a kennel for few days. Once the paint is properly dry and the area is well ventilated, you can bring back your pet in your house.
Check Your Pet’s Environment:
Once the paint project is complete, you should be aware of your pet’s environment and clean the place properly. Remove any loose paint chips from the area and make it clutter-free. This will keep your pet safe.
