Bradley Cooper treats pet pooches to spa day

London: `Hangover` star Bradley Cooper splashed out on a spa day for his beloved dogs to apologise for spending so long working away from them.

The star treated his pooches Charlotte and Sampson to a special day out at Los Angeles` exclusive Chateaux Marmont hotel where they were pampered and preened, a news website reported. "Bradley`s been travelling a lot and he felt guilty about leaving them. The doggie spa trip made him feel better, too!," a source said. During the day, the dogs were said to have given aromatherapy baths to spruce up their fur, massages to relax them and "pawicures" to keep their claws in tip top condition. Bradley is not the only celebrity to invest in beauty treatments for his pet. Last year, it was reported Jennifer Aniston, who Bradley was rumoured to have dated earlier this year, was paying USD 250 a week for her corgi-terrier Norman to receive massage, Reiki, and acupuncture treatments. "Norman has been Jennifer`s constant companion during all her emotional upheavals, but he suffers from aching joints and stiffness. Jennifer doesn`t want to put him on medication just yet, so she has opted for doggy spa treatments from a licensed vet technician," a source said at the time. PTI
