I have 2 dogs, Sparkles a 2.5 yr old maltese and Chilli, a 2 year old mini daschund. Chilli often licks Sparkles fur, it seems obsesive, her favourite spot is on Sparkles left side between her shoulder and hip. She has done this since a few days after I brought her home, at 9 weeks. At first I thought she was trying to get milk. Did she leave her mum too early? I keep Sparkles fur fairly short, otherwise it gets knots. I joke to family and friends that she has OCD, I was just wondering is it real? Thanks
