Nine days after the death of one of her many dogs, Lisa Vanderpump has lost another member of her menagerie.
The 57-year-old Real Housewives of Beverly Hills star posted a touching tribute to her Pomeranian named Pikachu on Instagram Thursday, writing, “Rest in peace my sweet Pikachu, we will miss you so much… Such sadness at your loss 😢.”
Her caption came attached to a gallery of sweet photos of the cream-coloured Pikachu through the years that captured him doing everything from playing in the grass of Vanderpump’s California home to hanging on a pilot’s lap in the cockpit of an airplane.
Pikachu, who was nearly 14 years old, was the second Pomeranian of Vanderpump’s brood to die in just over a week.
On September 26, the restauranteur mourned the death of her Pomeranian named Pink Dog. “Rest in peace Pink Dog,” she wrote on Instagram. “We are devastated to see you go so suddenly… you were such a happy pink dog and we will miss you dreadfully, we love you 💕.”
Back in 2013, Vanderpump revealed Pikachu had been hospitalized and diagnosed with Addison’s disease.
According to the American Kennel Club, the condition, which is also known as hypoadrenocorticism occurs when the adrenal gland (a small glad located near the kidney) fails to produce hormones and steroids that help regulate a dog’s internal organs and body systems. Without them, a dog’s body deteriorates — leading to serious complications and even death.
While there is no cure for Addison’s disease, it can be treated with replacement hormone medications, usually one injectable mineralocorticoid and a daily steroid.
Symptoms can include anything from poor appetite and lethargy to vomiting, diarrhea, shaking, and hair loss.
