Instead, you may allow your dog to run off-lead in most areas - but your dog must be under control/in sight at all times. Voice control is control.
Be aware that you are sharing the area with others who wish to enjoy open spaces: hikers, cyclists, horse riders, etc., as well as other dog walkers. CH and ZH are generally dog friendly, but be courteous to others - and remember that your dog's right to run off lead is secondary to other people's right to enjoy the outdoors without being bothered.
The general etiquette is that one shouldn't allow a dog to approach a person/other dog without asking permission first. If another dog is on lead this is a signal that the owner does not want interaction - so one should re-leash or recall one's dog until that person passes by.
Dogs are generally forbidden from swimming areas, from cemeteries, from play grounds and schools. The Gemeinde may also require dogs to be kept on lead in other areas - watch for signs.
In the forests, dogs should be on lead/under control in the spring when wildlife are rearing their young, and in the fall during hunting season for obvious safety reasons. Dogs are almost always required to be on lead in nature conservation areas.
If your dog is one of the restricted breeds the above doesn't necessarily apply - you'd need to follow the muzzling/leash laws as per your permit.
(I assume this is not the case, though, as you have just moved here and those 8 breeds have been banned since the start of the year.)
A summary of dog control laws in ZH can be found here:

And the brochure detailing the new ZH Hundegesetz can be found linked to post #8 in this thread:
Dog licence renewal in Kanton Zürich; Aaaarrgghhh
But as mentioned above, Switzerland is generally still a dog friendly country. Yes, common sense and courtesy are expected from owners - and most dogs lead very nice lives here.
Hope you and your pooches enjoy your time here.
thnx
One problem with Irschel park, though, is that it can get quite marshy if it rains.
Does it mean they break the law?
That;s the picture of the fountain:
Are there signs posted forbidding dogs, or requiring dogs to be on lead in that area?
Very broadly speaking, in KT ZH dogs are allowed wherever they are not forbidden. Even in areas falling under a general ban (cemeteries, Badis) you will usually see a 'no dogs' sign. If there isn't a sign, it is often a safe assumption that they are allowed - especially in mixed-use areas.
If you have questions, best to go to the source - contact the park authority/Gemeinde and ask if dogs are allowed, or not.
I'll check it with local authorities.
