I'm getting an Australian Cattle dog. I do field work most of the week and the dog will be with me working and I weekends he will also be outside hiking, swimming, or playing Frisbee or flyball. However, some days I will need to go into the lab where the dog cannot come. The dog won't be alone very long, a maximum of 6 hours twice a week. (I make my own hours so I can adjust it for the dog)
Before I leave the dog home I'm going to run him/her for a few miles to get him/her tired. Then I was going to crate him/her while I was gone with some toys.
My question is what kind of toys will keep an active, intelligent dog engaged so he/she does not become bored and destructive. I was recommended a kong but I don't know if that will be enough. Will the run and toys be enough to keep a pup happy for 6 hours?
One the pup gets older he/she will not be restricted to the crate but will be able to play in half the house (other half is for the cats to get away if they don't want to play with the pup) Any advice for toys for the dog?
Note: I don't want to leave the dog outside unattended so it will be in the house when I'm away.
Thanks for the help.
