With vog forecast to dominate the skies over most of Hawaii this week, people with respiratory issues are advised to take necessary precautions. But humans aren't the only ones impacted by vog, pets need protection too as some suffer allergic reactions to the volcano's fumes.

Darin Lee considers his two Keeshond dogs his daughters. Sasha and Keisha are inseparable and always fighting for their dad's attention.

"When I give a treat they look at me like, 'Why did she get the bigger one,?'" Lee said.

Eight-year-old Keisha is the older of the furry pair and struggles to breathe whenever the vog thickens.

"Keisha will start yacking. Yacking sounds like there's a fork stuck in her throat," Lee said.

Dr. Richard Fujie of King Street Pet Hospital said his patients have sometimes come in for issues relating to vog. The longtime veterinarian stressed the importance of listening for symptoms your dog might have when the haze moves in.

"Coughing would be the most common problem, coughing and panting. For those dogs, we tell them to keep indoors when it's voggy," Fujie said.

Fujie recommends dogs sensitive to vog avoid any strenuous activities and be kept inside with a cooling system.

"Air-conditioning would be best, so it's filtered air. Indoor would be the best things for pets," Fujie said.

Vog can also take a toll on cats, especially those with asthma problems. Dr. Fujie recommends an inhaler to alleviate breathing issues for cats that have feline asthma.
