Question Can you see an ACL tear coming?

Can you look at a puppy or the parents and tell if the dog is more likely to have ACL problems? I have been told that the angle of the back legs can really be tip off to future problems,

Yes, typically if the dog has poor angulation being very straight in the rear there is more of a chance of damaging the acl.

When one of my dogs tore his ACL, the vet said when she looked at his conformation, he was prone to it. That was the first time I've ever hear this. He tore both ACL's within 2 years.

i think that conformation is a factor, yes, but it's certainly not the only factor. luce is too straight behind and has torn both, but i've seen dogs with worse hind ends who haven't torn either. i've seen dogs with good angulation tear them. weight, fitness level, play/exercise style, age of spay/neuter all play a role as well.

I understand the weight and fitness level (pretty clear why) but what about Spay/Neuter? Are spayed/neutered dogs more likely to tear or rupture?

I found this JAVMA article:

[snip]

Conditions with increased risk (for early age gonadectomized dog)
1) Urinary incontinence (female, 12.9% of dogs spayed <3 months vs. 5% of dogs spayed >= 3 months, not associated with increased rate of relinquishment)
3) Hip dysplasia (incidence 6.7% early vs. 4.7% traditional: > 5.5 months had 3 times increased euthanasia for hip dysplasia)
4) Cystitis (female- not chronic)
5) Aggression toward household members (male, associated with increased risk of euthanasia) 2, 3
6) Barking (male, at visitors, bothersome barking)
7) Noise phobia
8) Sexual behaviors
9) Urination when frightened
10) Parvovirus (within first week after adoption)

No effect (dog): mortality rate, acariasis, allergic skin disease, balanoposthitis, cardiac disease, fractures, hyperactivity, hypoadrenocorticism, hypothyroidism, neoplasia, aggression toward animals, destructive behavior, digging, excessive licking/chewing skin, playful behavior, shyness, abscesses, aggression toward veterinarian, food allergy, demodicosis, fight-bite wounds, gingivitis, hit by car, kennel cough, intervertebral disk disease, lacerations, orthopedic problems of the stifle joint, perivulvar dermatitis, pica, pyoderma, repeat infections, soft tissue injuries

I've heard of an increase of soft tissue injury in pediatric spayed/neutered dogs, but I think there is only anecdotal evidence of this.

I had an Am Staff who had horrible HD in both hips and an ACL tear ... all by 1 yr of age. When I look back, he was just 'loose' in general, had poor angulation, limited rear leg muscle development (with proper exercise and other dogs in house were nicely muscled) and did the classic 'bunny hop' when he ran. If I were to get another, I'd want to see awesome muscle development, or I'd be leery.

Spay neuter of big breeds early too early accounts for a 2-3 inche growth in height that would not normally happen. THen them often put weigth on too. THis on a breed who has min angulation POP goes ACL.

I have neutered male with partial tear - I use breeders choice active care and no surgery
