Jax is never far from me. I want to crate train him but he just never stops barking and howling I am not sure how to train him to be ok in his crate and that it is safe there when I am gone. I work from home so I don't need him in the crate often or long. Also he does not understand my older dogs cues to leave him alone. I am worried he will get hurt.

It sounds like Jax is really bonded to you, which is sweet — but I can hear that it's also creating some real stress for both of you. These are very common challenges, especially with a dog whose age and background are unknown, and there's a lot you can do to help him feel more settled.

The crate barking and howling

What you're describing — the non-stop noise when he's separated from you — is often connected to something called separation anxiety (basically, a dog who feels genuinely panicked when apart from their person, not just bored or stubborn). The good news is that crate training can work, but it usually needs to go much more slowly than people expect.

A few general starting points:

• Make the crate a good place first. Leave the door open and toss treats or a favorite toy inside throughout the day. Let Jax wander in and out on his own terms with no pressure.
• Feed meals near or inside the crate. This builds a positive association at a time when he's naturally motivated.
• Start with tiny separations. Close the door for just a few seconds, then open it before he has a chance to get upset. Gradually — over days or even weeks — extend the time.
• Cover the crate. A blanket over three sides can make it feel more den-like and less exposed.
• Calm arrivals and departures. Big hellos and goodbyes can actually increase anxiety. Keep it low-key.

Since you work from home and don't need long stretches, you're in a great position to go at his pace.

The older dog situation

This one is worth taking seriously. Dogs do communicate with each other through body language — a stiff posture, a hard stare, a low growl — and a younger or newer dog who doesn't read those signals can end up in a scuffle. You're right to be watchful. Supervising their interactions closely and giving your older dog a space Jax can't access (a baby gate works well) can prevent a lot of conflict while Jax learns the household rules.

When to see your vet:

If Jax's distress in the crate is intense — drooling, panting heavily, injuring himself trying to escape, or not calming down at all even after weeks of slow training — that level of anxiety often benefits from professional support beyond basic training tips. A vet visit would be a good idea to:

• Rule out any underlying health issues contributing to his anxiety
• Discuss whether a referral to a certified animal behaviorist makes sense
• Talk through options for managing separation anxiety more effectively

I'd recommend scheduling a visit within the next few weeks if things aren't improving, or sooner if you see any signs of self-injury or if a scuffle with your older dog occurs. You're clearly paying close attention to Jax — that's already half the battle.
