Today, in London's Hyde Park, on tiny pet headstones dating back to the 1800s you can still read, "Not one of them is forgotten before God."
In the U.S., pet funerals and burials are "definitely an expanding market," according to Robert Fells of the International Cemetery, Cremation and Funeral Association.
To accommodate interest some cemeteries are dedicating new sections specifically for the purpose. Due to legal restrictions and sensitivities existing areas are not allowed to expand to include pets.
Back in the UK, Penny Lally is all for expanding the market and offering pet owners a choice they may not know they have when their four-pawed friend passes away. "We treat them all with great respect," she says.
As for Lally, she plans to be buried alongside her dearly loved horse, Super Sam. She already has the perfect spot for Super Sam and his tree in mind.
