Hunter hasn't lost any of his baby teeth and he is 4 months old. I have been checking his mouth for the last month to see if he is losing any, but there all still the same. Should I make a vet appointment? Or just wait it out for a little while?

We give him hard bones and hard toys to play with which we thought might help him lose them (compared to stuffies) but there still there and none are even lose.

Im starting to think he is younger than what I was told (which would kind of explain his aggression, which by the way has diminished greatly), and it would make sense since they lied to me about his breed...

Think you are jumping the gun a little bit and worrying too much, normally puppies start losing their baby teeth at four months, so he is not behind schedule in that regard.

Okay thank you,
Everyone who I've talked to has said he should start losing them at three months, so I was a little concerened on why he hasn't lost any.

Hasn't your Vet been able to tell you a fairly accurate age for him?

Nope, when I took him in the vet asked how old he was (Which I said 10 weeks since that was how old I though he was), and she never questioned it. But now he hasn't lost his puppy teeth, there is no sign of his teste's (Which I've talked to someone about and they should start to show now as well)... Maybe I'm just being concerned... On a side note to anyone who has been following his story... I really think he was abused, and the people I got him from lied about a lot (For instance, he is no way boxer rotti), because now that he has settled in (almost 2 months later) he is starting to warm up to people and will cuddle, but he hates new people even though he has been introduced to lots of people since I got him. He also shows fear if you go to lift your hand to pet him, he cowars, before he'd go to bite, so I'm thinking his aggression is a mix of abuse and being taken away from his mom to soon, but with lots of love and attention he is starting to understand that Im not going to hurt him, and he only cowars if I am standing, so I get down on the floor to play with him and he is okay with that, its going to take a lot of time but I see him being one of the best dogs I've had, he is super smart!

I would be more worried about the lack of testes than the lack of adult teeth.

Crypotorchidism and monorchidism is fairly common in some lines and he will need to be neutered early to remove the retained testes.
Testes that remain inside the dogs body and do not drop are more likely to develop cancer.

The teeth are normal, he may well be a bit younger than you though, or just late at losing them.
Some dogs do retain baby teeth and need them pulled but I don't think you have to worry about that just yet.
Vet swill not pull baby teeth without signs of adult teeth erupting.

My Chinese Crested is now 14 months old and still has 2 baby canine teeth. There is no chance of adult teeth coming through now, I just have to make sure I keep them nice and clean so they do not rot and they will stay in place for years.

Okay, when should I start to worry about the testes and make an appointment with the vet? He went for his first shots and boosters.. but with his little emergency eating a thorn bush I don't really have the money to waste, so I'd rather bring him in when he needs it (instead of every time I worry)...

Ok reading back my post sounded more serious than I intended!

No, you won't need to go to the vet yet. Testes should be down by 6 months so you have a couple on months up your sleeve before you have to worry about having them checked.
They still could drop in the next few months it is just more and more unlikley as more time passes.

Just keep an eye on his teeth.
If you notice an adult tooth erupting in front or behind a baby tooth and not pushing the baby tooth out, you can try just wobbling the baby tooth a few times a day with your thumb.
If that doesn't work then it will need to be pulled.
