I'd find somebody who has terriers and ask what toys are lasting them the longest. They should be a similar size to your puppy and terrier teeth/determination makes them hard on toys. I'd hesitate to suggest anything because I don't know what you have in Italy.

Kongs are great! They are the only thing I feel safe leaving with my dog that gulps chews. They have a puppy version that's softer.

Many of the dog puzzle toys are only hard from a human perspective because we think in terms of hands. My parents have a Boxer who has figured out every "difficult" puzzle toy he's been shown in less than a minute. He just tips it on it's side or upside down and shakes until all the sliders, cups, whatever reach the right position and dispense the treats. He's a smart food driven boy though. Other dogs get more entertainment from it.

If you want to challenge your dogs brain there are several books on the market that are basically just lists of dog tricks. I like to flip through and randomly pick one out when Tanner is bored. I normally use a clicker with them just because it is faster.

I've owned half a dozen different terrier breeds over the years.

Same as other "breeds" some don't damage toys to any great extent and some can destroy even the black Kongs in a matter of days.

The black Kongs probably do hold up better then most.

different strokes.

Instead of arguing opinions and theories about crating dogs, I dare say that the proof is in the pudding. I have experimented with this, and have my dog's take on it.

When I adopted my mature GSD, I went the first month without a crate. I had no idea how much my dog valued a crate. I gave her free run of the front (uncarpeted) rooms of my home. At first, I had to block off the sofa until she learned how I felt about animals on human furniture, but that ws her only conflict and otherwise was a perfect house dog.

Later, I had a talk with her previous owner, and learned that she not only was crate-trained, but pbly missed her crate. I asked around and was given a used large wire crate. I couldn't believe my eyes! She not only was obviously acquainted with the concept, but there were certain times that she crated herself.

My dog now has an open crate in her top spot. I removed the door so that she can enter and exit at will. Sometimes she sleeps stretched out on the cool tile and other times, such as when she's really tired or if I stay up late, she will retreat to her crate. If someone comes to the door, I can send her to the wide-open doorless crate and she will go in and stay WITHOUT A COMMAND until released. If I gripe at her for being in the kitchen during food prep or if I call her a "bad dog" due to some transgression, she will slink off to her crate and hide there until I calm down. If she has a knucklebone and I tease her by acting like I'm going to take it, she will take her bone and retreat into the crate.

Y'all can argue about instincts and ancestors and all that junk, but I'm with my dog on this one. She's never lied to me and she's smarter than most of us here.

One more thing, FWIW... I've built doghouses for my outside dogs, and every one of them burrowed under the dog house and built a den under the house. I switched to building low decks on the shady side of the barn. The dogs dig dens under them and lay out on top of them in sunny cool weather.

Just a comment on toys, rubber, or toys of any kind for that matter...

Spent a bunch of money getting a chunk of rubber toy out of the digestive system of an 8 month old GSD.

As long as you are vigilant, and watch the size of the toy, and note when it might be getting to a used point where bite sized chunks can be ingested, and you remove the toy... OK.

Just saying... Some things don't get digested, don't pass, and can be a blockage that can be fatal in a matter of hours.

Young dogs will eat anything, so be alert. For that matter, any dog will eat anything, so be alert.

Mike, I've paid for that same bowel obstruction surgery too for a hunk of stuck rubber. As well as the cost of a broken tooth extraction on another one. My policy now is that dogs don't have toys at all unless I'm in the same room. And they don't get them for very long. And no puppy gets any soft bedding.

On crating a dog.

How many of us have had small dogs that loved to sleep under our beds?!

Dogs love the small confinement of their "cave".

Introduced correctly and not used to "punish" the dog I think a crate is an extension of these "caves".

Security!

I agree that crate training is an essential skill for a dog to know...

GOOD

I think dogs are as much wolves as Budgerigars are eagles, jmo.

LOL, your opinion is wrong on this one, my cyber buddy -- Budgies and Eagles are Two DIFFERENT Species that will not & cannot interbreed to produce viable offspring ... Dogs and Wolves are members of The SAME Species that can & will interbreed to produce viable (and fully reproductive) offspring. Dogs most definitely appreciate having a DEN

Yup. Canis lupus. We have certainly selectively bred out some wild wolf behaviors (especially flight distance from humans), but the dogs living with us are more like wolves than not. Canids have existed for millions of years, but only lived with humans for a few thousand. Their instincts for social structure (and the way they communicate that structure), territory marking, and den-making are hard wired. It's what makes them canids. No female canid would whelp a litter without first improvising a den.

The distinction between "wolf" and "dog" is a human invention, not much different than the distinction we see between "retriever" and "mastiff." Nature doesn't see this difference. If two individuals can produce fertile offspring, they are part of the same gene pool.

Yessiree, and in Australia it'a Canis lupus dingo (a sub-species of the grey wolf) but which used to be classified as Canis familiaris dingo (a sub-species of the domestic dog) -- LOL, taxonomy is definitely a human invention ... Some genetic zoologists currently believe dingoes should just be designated as Canis dingo, period

or it could be that dogs and wolves branched from a common ancestor which seems the way the thinking is going with mitochondrial research, at least as far as this layman can figure it.

disclaimer: my biology knowledge is low level.

the dingo classification can not be separated from political pressure - aussie farmers have a long history of hysterical and irrational reaction to anything that threatens sheep populations. (refer the extinction of the Tassie tiger).

forcing a classification politically that the dingo is just a domestic dog gone wild ie a feral pest conveniently undermines efforts to give it wild species status which would entitle it to protection by the state.

as far as behaviour traits I am even more sceptical of the wolf & dog thing, yeah they pee & poop the same, big deal.

I have never seen a wolf but from the disasters I have read involving the pet wolf/hybrid trade there is a parallel with the dingo pet/hybrid trade as far as behaviour.

if you have ever followed wild dogs and dingoes (and presumably wolves) in the wild they are not the same thing, hunt, fight, breed, range differently.
