Hi there,
We use a kennel/cattery which is based in the countryside outside Tatroz, near Châtel St Denis. Myriam is really good with animals and speaks English too.

They are priced reasonably too. Our Bernese Mountain Dog is sometimes put in for day when we go skiing and it only costs us 18CHF.
Hope this helps.
