but rest assured that absolutely pure Havanese can inherit the "digging gene" too.
True, Ricky is a digger too. He doesn't dig to bury things, he just likes to dig. Inside the house it is carpet, furniture, doggie day bed, crate mats, anything! Outside is in the garden where he will dig like a maniac for 10 seconds and them go chase a blowing leaf.
Another thing that many breeders do, and might satisfy Teddy's digging instincts is the fill a small kiddie pool with either small plastic balls or small, empty, water bottles. They make a nice, satisfying crackly noise and many dogs find them irresistab
Ricky loves, loves, loves empty plastic water bottles, the bigger the better! He prefers the one liter size. The crackly noise gets him all worked up. We always remove the label and the plastic retaining ring at the neck of the bottle, and the cap. Ricky can shred one of these bottles in as little as 10 minutes so we watch him carefully when playing with a bottle. We don't want him ingesting any plastic.
I found an old soccer ball in the bushes along the road the other day. I brought it home and Ricky was enthusiastic and is very good at playing soccer. He can guide the direction of the ball with his snout. Well, that game lasted all of about two days! Ricky was able to make some tears in the covering of the ball and then he started shredding it. End of soccer ball! Ricky is getting a present for Christmas that hopefully is more durable. But that is a secret until Christmas.
