First the HSCT is very challenging for most people in two days with a pack and should not be considered lightly with a dog.
The HSCT is doable with a large dog with a lot of agility and comfort over challenging terrain, 3m+ vertical decents/accents, scree, large jumps along narrow passes. It is often mine would have to find an alternate route to meet up with me.
The E side of the W Lion could be covered in snow. This is more a challenging sidehill with snow bridges and running water that need careful attention.
Either David or James Pk has two spots where dogs need a boost on the S ridge accent near the summit.
Lastly, the entire HSCT is exposed to sun in Aug and there is very little water. Heat injury and dehydration would be a big consideration. There is little water aside from occasional snowpacks in early season so you will need a huge amount of water upwards of 6-8L with a medium dog on a hot cloudless day.
