Can anyone guess what dogs these hybrids are made up of? (they're all 2 different dogs in one)?

They aren't hybrids. They are mutts.

Sheltie

Corgi

Papillon

The pix of the last one looks like it is a larger size and the way the dog is laying, hard to tell.

I would say Wire haired chihuahua and maybe something else added but the wire haired ones look much like the pix you have posted.

Some people are calling such breeds as a peekapoo a hybred dog. personally, I call them mixes. Nothing wrong with a dog that is a mix. the majority of breeds started as mixes until a type was set for so many generations and then approved as a breed.

They are all quite cute.

1. Sheltie / Chichacha

OR... Shih-Tzu / Corgi

OR... Chichacha / Shih-Tzu

2. Chihuahua / Papillon

OR ... Cavalier King Charles Spaniel / Papillon

3. Chihuahua / Toy Fox Terrier

OR ... Shetland Sheepdog / Shiba Inu

OR ... Pomeranian / Chihuahua

OR ... Chihuahua / Jack Russell Terrier

OR ... Italian Greyhound / Chihuahua

OR ... Chihuahua / Dachshund

As you can see, I believe Chichacha is part of the mix in all three.

Hybrids are two SPECIES mixed, NOT BREEDS.

1. Papillon Mix

2. Papillon Mix

3. Papillon Mix

I'm almost positive the second one is a chihuahua/corgi mix, the first no idea but the third is maybe an american eskimo mixed with something I can't place =/

A papillon and a miniture pinscher maybe?! i dont really know! whats the awnser

A hybrid is a cross between two species, such as corn and tomato, cat and dog, snake and rabbit, none of those are hybrids.

the third photo appears to be a cat with a mini-dog head.

I would say welsh corgi and papillon

They all look like Papillon crosses to me. :-(
